Toyota P2118 trouble code?

When the engine control module (ECM) detects out-of-range voltage or poor performance from the throttle actuator control motor, the P2118 code is set along with a Check Engine Light on the dashboard. When the P2118 code is set, it also triggers a failsafe mode to prevent damage to the vehicle.

  • P2118 is a diagnostic trouble code (DTC) for ‘Throttle Actuator Control Motor Current Range/Performance’. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What does code P2118 mean?

Error Code P2118 is defined as Throttle Actuator Control Motor Current Range/Performance, which usually happens due to wiring or throttle motor issue. This error code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II system, especially those made since 1996 up to present.

What is code P2101?

Diagnostic Trouble Code (DTC) P2101 stands for Throttle Actuator “A” Control Motor Circuit Range/Performance. It is usually triggered when your vehicle’s powertrain control module (PCM) detects that the actual throttle position does not match the desired throttle position.

Where is the throttle actuator control?

The throttle controller is located on top of the engine between the air intake and the intake manifold.

How do you fix a throttle actuator control system stuck open?

What repairs can fix the P2111 code?

  1. Replace the TPS. Commonly this will require the throttle body to be replaced as the TPS and the throttle body is an integrated unit.
  2. Clean the throttle body.
  3. Replace the throttle body.
  4. Replacing the PCM. (
  5. Repair the wiring.

What happens when the electronic throttle control goes bad?

When a TPS goes bad, then the car’s throttle body won’t function properly. It could either stay shut or it won’t close properly which is a severe issue. When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle.

Where is the TAC module located?

The TAC module is mounted on the driver’s side firewall under the corner brace.

What is the code P2135?

Diagnostic trouble code (DTC) P2135 stands for “ Throttle/Pedal Position Sensor/ Switch A/B Voltage Correlation.” This code appears when your car’s primary computer, which is often referred to as the powertrain control module (PCM), detects a problem with one of throttle and/or the pedal position sensors/switches.

What’s the code P2176?

The P2176 trouble code indicates that the Engine Control Module (ECM) has detected that the throttle body actuator/motor has failed to learn the correct position at which the butterfly valve within the throttle body should be in order to produce a smooth idle for the engine.

How do I fix code P2100?

What repairs can fix the P2100 code?

  1. Replacing the throttle actuator assembly.
  2. Repairing the wiring or connection to the actuator assembly.

What is code P2110?

P2110 is an OBD-II generic code for the engine control module (ECM) detecting a major failure in the throttle actuator control (TAC) system causing the ECM to go into failure mode and limiting the engine to a specified RPM limit.

What does engine code P2111 mean?

The error code P2111 usually refers to the throttle actuator control system which is stuck open. Depending on the driver’s request for power, the throttle motor will open and close the throttle plate by allowing more or less air to pass through the engine.

P2118 Throttle Actuator Control Motor Current Range

What does that mean?

It is likely that this generic powertrain diagnostic trouble code (DTC) will apply to any vehicle equipped with an OBD-II system and using a drive-by-wire throttle control system, including but not limited to vehicles from Toyota, Honda, Hyundai, Lexus, Volvo, Scion, Nissan, Kia, and other manufacturers. The P2118 OBD-II trouble code is one of a number of possible codes that indicates that the Powertrain Control Module (PCM) has detected a malfunction with the operation of the Throttle Actuator Control System.

THrottle Actuator Control System failures are signaled by six different codes:P2107,P2108,P2111,P2112,P2114, P218 and P2119, which are all related with the Throttle Actuator Control System.

The Throttle Actuator Control System is controlled by the PCM, which keeps track of the position of one or more throttle position sensors.

In addition, the PCM monitors the accelerator pedal position sensor to identify how fast the driver want to travel, and then decides the proper throttle response to match the desired speed.

In some cases, the PCM will cause the Throttle Actuator Control System to be unable to operate properly.

Code SeveritySymptoms

Depending on the individual fault, the severity of this code might range from moderate to severe. Among the possible symptoms of a P2118 error code are:

  • The engine will not begin to run. Poor performance that worsens with time
  • There is little or no reaction from the throttle
  • The Check Engine Light has been lit. Smoke coming from the tailpipe
  • An increase in the amount of gasoline consumed

Common Causes Of A P2118 Code

The following are examples of possible reasons of this code:

  • Troubleshooting: Bad throttle body
  • Dirty throttle plate or linkage
  • Faulty throttle position sensor
  • And bad accelerator pedal position sensor. The control motor for the throttle actuator is faulty. Connector that has been corroded or damaged Wiring that is faulty or damaged
  • A faulty PCM

Common Repairs

  • Replacement of the throttle body
  • Cleaning of the throttle plate and linkage
  • Replacement of the throttle position sensor
  • Replacement of the throttle actuator control motor
  • Replacement of the position sensor for the accelerator pedal
  • Connectors are being cleaned of corrosion. Wiring repairs or replacements are required. Changing the PCM (flashing it or replacing it)

Diagnostic and Repair Procedures

It is necessary to do a thorough search for Technical Service Bulletins (TSBs) for a certain vehicle by year, model, and power plant before beginning the troubleshooting procedure for a given failure. Depending on the situation, this might save you a significant amount of time in the long run by directing you in the appropriate route. To complete the second step, you must first find all of the components that are connected to the throttle actuator control system (TACS). If you have a simplex system, this will comprise the throttle body, the throttle position sensor, the throttle actuator control motor as well as the PCM and the accelerator position sensor.

The next step is to inspect the connections to each component for security, corrosion, and broken pins, among other things.

If you press in on the throttle plate while the ignition switch is off, you should be able to spin the throttle plate. It should be in the wide open position when it is rotated. Sludge behind the plate should be removed while the plate is still accessible to ensure proper cleaning.

Advanced Steps

The advanced phases become quite vehicle specific and need the use of specialized equipment in order to be performed properly. In order to complete these operations, a digital multimeter as well as the vehicle’s particular technical references are required. According on the year, model, and engine of the car, the voltage needs will differ significantly.

Circuit Checks

Disconnect the electrical connector at the throttle body while the ignition switch is in the ‘off’ position on the car. On the throttle body, look for the two pins that connect to the motor or motors. Using a digital ohmmeter with the resistance setting set to ohms, measure the resistance of the motor or motors. Depending on the vehicle, the resistance of the motor should be between 2 and 25 ohms on average (check manufacturers specs for your vehicle). Depending on whether the resistance is too high or low, the throttle body may need to be changed.

The presence or absence of a power supply or ground may be detected during this procedure; hence, continuity testing may be necessary to ensure proper wire integrity.

Resistance or a lack of continuity is a symptom of bad wiring, which must be rectified or replaced immediately.

1 non-operational battery When leaping, it is necessary to cross polarity. 3 Failure to execute a throttle body relearn after removing the battery is a serious violation of the law. When the engine is turned off, the Toyota Electronic Throttle Control System (ECTS) maintains a tiny opening in the throttle body, indicating that it is electronically controlled. When evaluating the status of the ECTS with the engine turned off, you should see that the throttle plate has been split open by 5.5 degrees (see illustration).

The ECM ceases providing power to the ECTS during a fail-safe mode, but it still lets you to drive by managing the fuel injector and ignition timing to response to your accelerator pedal inputs.

This enables you to drive even if your ECTS has failed, although at a reduced speed. If your battery is dead or if you have recently changed your battery, you must undergo an idle relearn procedure. If you do not follow these instructions, the throttle body may not function correctly.

Toyota Throttle Body Idle Relearn

Turn off the ignition and wait for at least 30 seconds after turning it off. Start the engine and let it warm up until the engine coolant temperature reaches 80 degrees Celsius (176 degrees Fahrenheit) or higher. Following engine warming, turn off the air conditioner and all other equipment and let the engine idle for 5 minutes without moving the vehicle. Check to verify that the idle speed is within the normal operating range.

Other Toyota P2118 trouble code tests

Please see the schematic below for the Toyota throttle body wiring. Check the voltage of the battery at the throttle body connection M2. Verify that the throttle body connector M1 is grounded. Disconnect the connector at the throttle body and measure the resistance across M1 and M2. If you have both, replace the connector at the throttle body. 0.3-100 degrees Celsius should be visible at room temperature. If this is the case, you may have a faulty throttle body.

P2118: Throttle Actuator Control Motor Current Range/Performance

Throttle Actuator Control Motor Current Range/Performance is specified as the cause of Error Code P2118, which is often caused by a wiring or throttle motor malfunction. It should be noted that this error code is a generic difficulty code, which means that it applies to any car equipped with an OBD-II system, particularly those manufactured from 1996 to the present. Of course, the specifications for the definition, diagnostics, and repairs differ from one make and model to the next depending on the manufacturer.

Definition

Automobiles fitted with electronically controlled throttle bodies are sometimes known as drive-by-wire vehicles since the throttle actuator control motor is located in the vehicle’s engine compartment. Using this type of technology, the gas pedal serves as a sensor, sending signals to the throttle actuator control motor, which then opens and closes the throttle position in response to demand. When the PCM (powertrain control module, also known as the ECM or engine control module) determines that the voltage is out of range or that the throttle actuator control motor is performing poorly, it will set the Error Code P2118 and simultaneously illuminate the Check Engine light on the instrument panel.

This mode helps to keep the vehicle safe from further damage by limiting the vehicle’s operation.

Common Symptoms

This error code, like all other error codes, causes the Check Engine light on the dashboard to illuminate and the code to be stored in the vehicle’s memory. Additionally, it might create significant symptoms, such as the car not reacting to the gas pedal owing to the failsafe mode being activated on the vehicle. Other frequent signs and symptoms are as follows: In certain cars, the Check Engine light may not illuminate until after the symptoms have manifested themselves.

Possible Causes

The registration of this code is the result of a number of circumstances, including:

  • The throttle actuator control motor has failed, as has the pedal position sensor, which has failed, as has the throttle position sensor. An open or a short circuit in the actuator circuit
  • Electrical connection that is not up to par

How to Check

Mechanics diagnose this code by scanning the vehicle’s PCM using a scan tool to look for any codes that have been saved there. All of the codes, as well as the code history and pending codes, are written down. Additionally, each code will have its own freeze frame data linked with it; this information informs the technician about the status of the vehicle at the time the code was initially saved. After that, all of the codes are cleared, and the car is put through its paces for a test drive. If the code is still present after the test drive, the technician will proceed to the next step in the diagnosis.

The scan tool will be used to monitor the data stream and to evaluate both the throttle and gas position sensor readings as they are read out when the vehicle is in operation.

Finally, the technician will remove the air intake and throttle body in order to inspect them and determine whether or not the throttle plate is capable of being moved.

How to Fix

This error number is simple to correct, but it does need a thorough investigation to determine the cause. The following are examples of typical repairs:

  • Wiring harness repair or replacement in the event of damage Repair or replacement of the throttle actuator control motor
  • Repair or replacement of the pedal position sensor
  • Repair or replacement of the throttle position sensor that has failed
  • Poor electrical connections are repaired or replaced.

Many individuals misdiagnose or make mistakes when dealing with this error code simply because they fail to see the need of performing a complete visual check. In many circumstances, the only thing that needs to be done is to locate the frayed wires and fix them. It is critical to complete all procedures in their appropriate order and in their entirety prior to beginning any repairs or modifications. The failure of the throttle to operate correctly as a result of this code putting the car in failsafe mode can result in major consequences.

It is thus necessary to treat this code with extreme caution, and the vehicle should not be driven until the problem has been resolved.

If you do not have access to this tool, it is recommended that you seek the assistance of a professional technician to resolve this error code.

We strongly advise you to Torque Pro is a software program that allows you to control the torque of a motor.

What Does Code P2118 Mean?

Fault code for the OBD II It is defined as ‘Throttle actuator control (TAC), throttle motor current – range/performance problem’ and is set by the PCM (Powertrain Control Module) when the PCM (Powertrain Control Module) detects that the input voltage in the throttle control motor’s control circuit falls outside of the expected/desired range, or that the throttle control motor fails to perform as expected.

It is important to note that code P2118 is only applicable to applications that employ ‘drive-by-wire’ throttle control systems, in which there is no physical interface between the accelerator pedal and the throttle plate, as opposed to traditional throttle control systems.

To ensure proper operation of the throttle control system, a dedicated position sensor monitors the position of the throttle plate.

Operating in a similar manner to an electronic throttle, the PCM makes use of data from two or more variable resistance position sensors, which it utilizes to monitor and regulate the position of the throttle plate at all times.

A fully functional system responds to the acceleration or deceleration of the accelerator pedal by adjusting the resistance of the pedal position sensor, which causes the PCM to either open or close the throttle plate by an amount that corresponds directly to the position of the accelerator pedal in relation to a minimum stop position.

Consequently, if the PCM detects that the voltage in the throttle control motor’s power supply circuit has fallen below a predefined minimum threshold, it interprets this as a ‘range or performance’ problem, and it will set the code P2118 and illuminate a warning light as a result of the low voltage detection.

Depending on the application, throttle response may be severely reduced or stopped entirely, and in certain cases, it may not be able to start the engine at all when this happens.

Furthermore, regardless of the severity of the failsafe or limp mode, the program will continue to operate in limp mode until the problem is rectified or the error is fixed.

Where is the P2118 sensor located?

The illustration above is an example of a common ‘drive-by-wire’ throttle control system that is included into the overall throttle body assembly. Although the actual DC motor in this example is indicated by a red arrow, it is important to note that, while all motorized throttle control systems operate according to the same general principles, the appearance, design, and layout of individual components (in relation to one another) within the throttle body can differ significantly between applications.

It is necessary to replace the whole throttle body component as a complete unit in these instances.

What are the common causes of code P2118?

NOTE: Code P2118 is frequently associated with other throttle control-related codes, any one or more of which might have caused, or contributed to, the setting of code P2118 or any combination of them. In order to avoid a misdiagnosis and the needless replacement of parts and components, it is critical to resolve extra codes in the precise sequence in which they were set and saved. Nonetheless, the following are some of the most typical reasons of code P2118:

  • Corroded wire and/or connections in the power supply circuit for the throttle control motor
  • Damaged, burned, shorted, disconnected, or disconnected wiring and/or connectors in the throttle control motor’s power supply circuit Throttle control motor that is not working properly
  • Occasionally, malfunctioning position sensors might lead to the occurrence of code P2118. PCM has failed or is failing. Note that this is an extremely unusual incident, and that the defect must thus be located before any control module is changed.

2010 Toyota Camry P2118 ETCS Electronic Throttle Control System Problem – BackYardMechanic

When a friend of mine drove his 2010 Toyota Camry, he had a situation in which the car started but did not respond when the gas pedal was pressed. I ran MyOBD2 code diagnostic tool over the vehicle and it returned a P2118, which is the ETCS code. First and foremost, we still have an issue, which may be due to a defective ECM, but there are things to do first to rule it out. I’m presenting what I’ve discovered so far in the hopes that it will be of assistance to someone else who is experiencing the same difficulty.

  1. It is a 10 amp fuse with the marking ETCS on it.
  2. Before testing, the ETCS will need to be reset with the key turned off.
  3. A P2118 error code indicates that the Electronic Throttle Control System (ETCS) is not receiving power from the engine control module (ECM).
  4. P2118 Toyota Product Information ETC has a dedicated power supply circuit that powers the Electronic Throttle Control System (ETCS).
  5. When the voltage becomes unstable, the ETCS becomes unstable as well, causing it to become unstable.
  6. If the repairs have been completed and the system has been restored to normal operation, turn the ignition switch off.
  7. Here’s an illustration of what I mean.
  8. It is possible that the wire leading to it has shorted out or has an open and that it requires testing.
  9. UPDATE: It was discovered that the Camry had a faulty pin in the harness, which was rectified and the error was no longer shown.
  10. The ETCS itself is placed on the throttle body and may be examined using an Ohms meter to determine its functionality.
  11. If you need to remove the fuse box in order to locate a faulty wire, this tutorial will help you out.
