P0340 Jeep?


  • OBD2 Code P0340 Jeep definition: This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit – the sensor itself, the wiring, or the PCM.

How do I fix error code P0340?

What repairs can fix the P0340 code?

  1. Repairing or replacing the camshaft position sensor circuit wiring.
  2. Repairing or replacing the camshaft position sensor circuit connector.
  3. Replacing the camshaft position sensor.
  4. Replacing crankshaft position sensor.

Can you drive with code P0340?

How Serious Is Code P0340? – Severe. The vehicle may be difficult to start and the driver may also experience a lack of power when driving. It is possible for more damage to occur inside the engine of the vehicle if disregarded for an extended time period.

What does camshaft position sensor a bank 1 circuit malfunction mean?

P0341 code refers to a problem with the camshaft position sensor (CMP) signal on Bank 1. It could be that the signal coming from the CMP is not matching, not within the expected range, or not timed properly with the crankshaft position sensor’s (CKP) signal.

Can bad timing cause P0340?

One common mistake many people make when they see the P0340 is panicking over a faulty timing chain or belt. The P0340 clearly states that there is an electrical problem in the circuit to the camshaft position sensor. Therefore the P0340 trouble code is not caused by a faulty camshaft timing.

Can I drive my car with a bad camshaft position sensor?

Yes, it is safe to drive with a bad camshaft sensor. However, the performance of your engine will not be as good and fuel consumption may increase. In some cases, the camshaft may need replacement if there are any other symptoms of failure on this component.

What are symptoms of a bad cam sensor?

If your vehicle idles roughly, stalls frequently, has a drop in engine power, stumbles frequently, has reduced gas mileage, or accelerates slowly, these are all signs your camshaft position sensor could be failing.

Should there be oil on the camshaft sensor?

The camshaft sensor is inserted through an opening in the cylinder head and would necessarily be covered with oil. However the exterior part of the sensor, outside of the head, should not be covered in oil.

Is a camshaft sensor hard to replace?

It may be easiest to remove and replace the camshaft sensor from under your vehicle, but it can also be done from the top by removing the air filter housing. Oil and corrosion could affect the signal from the sensor to the engine control module.

How much does it cost to replace a camshaft sensor?

To replace a camshaft position sensor, you can expect to pay anywhere from $95 to $200. Parts alone will run about $25 to $100. Labor costs will be in the range of $70 to $100 for professional replacement. Expect to pay more if you have a luxury vehicle or are having your local car dealership perform the replacement.

Where is camshaft position sensor a bank 1 located?

Beneath the timing belt cover is where the CMP Sensor is mounted. The camshaft position sensor can be found in the right side of the engine compartment at the rear of the valve cover.

What can a bad camshaft position sensor cause?

A failing camshaft position sensor begins losing its ability to quickly transfer data. Mismatched fuel delivery and ignition timing, even if off by a few milliseconds, will cause your vehicle to sputter, accelerate poorly, lack power, stall or even shut off.

What side of engine is Bank 1?

Bank 1 and bank 2 simply refer to either side of the engine. Bank 1 is on the side with cylinder 1. Bank 2 is the side with cylinder 2. Most commonly Bank 1 is towards the front of the car if it has a transverse engine.

What’s the code for a bad timing chain?

Causes of Code P0017 If your vehicle does not have a variable timing system, it’s likely that the engine timing is off or that you have a worn or broken timing chain/belt.

What is code P0320?

Diagnostic Trouble Code (DTC) P0320 stands for “ Ignition/Distributor Engine Speed Input Circuit.” Since the PCM controls critical engine systems such as ignition and fuel delivery, to manage these outputs, it needs to know the rotational speed and positional data of the crankshaft.

What is P0012 code mean?

P0012 is an OBD-II generic trouble code which indicates a vehicle’s ECM (engine control module) has detected the intake camshaft timing on Bank 1 (number 1 cylinder side of engine) does not correspond with the intake camshaft timing (in degrees) which the ECM expected to find; the camshaft timing is over-retarded,

OBD-II Trouble Code: P0340 Camshaft Position Sensor Circuit Malfunction

Circuit Failure in the Camshaft Position Sensor System

What does that mean?

This diagnostic problem code (DTC) is a general powertrain code that may be seen on many vehicles. Although particular repair processes may alter significantly depending on the model, it is called general since it applies to all makes and models of automobiles manufactured after 1996. As a result, this page on engine codes applies to Nissan, Ford, Toyota, Chevrolet, Dodge, Honda, GMC, and other manufacturers. It is indicated by the P0340 error code that a fault has been found in the camshaft position sensor circuit.

Don’t just replace the CPS (camshaft position sensor) and assume that this will solve the problem completely.


Symptoms can include any of the following:

  • Starting up is difficult, or there is no start at all. Inconsistent running and misfiring
  • Engine power has been reduced.


A code P0340 might indicate that one or more of the following events have occurred:

  • The circuit could be compromised by a grounded, shorted, or damaged wire or connection
  • The camshaft position sensor might have failed
  • The PCM could have failed
  • There could be an open circuit
  • The crankshaft position sensor could have failed
  • And so on.

Possible Solutions

When dealing with an OBD-II issue code such as P0340, diagnostics might be difficult at times. Here are some ideas to get you started:

  • Using a magnifying glass, visually check every wire and connection in the circuit. Verify that the circuit wire is still connected
  • Verify that the camshaft position sensor is operational (that it is producing electricity)
  • Whenever necessary, replace the camshaft position sensor. Check the circuit for the crankshaft position as well. When necessary, replace the circuit wire and/or connections. If necessary, diagnose and replace the PCM.

Jeep Wrangler P0340: CPS – Circuit Malfunction

P0340is a difficulty code that is both rather frequent and difficult to identify. No exception may be made in the case of theJeep Wrangler This is due to the fact that it is a general powertrain code. Generic error codes inform you that there is a problem, but they do not provide any information about which specific portion of the system is causing the error. CPS (Camshaft Position Sensor) circuit failure indicates an OBDII code of P0340 on the vehicle’s instrument panel. While it may be tempting to swap in a new camshaft position sensor and see if that solves the problem, the CPS does not always work to resolve the issue in question.

We’ll go through the symptoms and possible causes of P0340 in your Jeep Wrangler in the sections below.

P0340 Symptoms: Jeep Wrangler

The CPS assists an engine in determining the most ideal time for combustion to occur. In the event that it is not operating effectively, it might create several driving difficulties in your Jeep Wrangler. They are as follows:

  • The inability to start
  • Poor idle quality
  • Decreased fuel economy
  • And a decrease in engine power

Jeep Wrangler P0340 Causes

As previously indicated, the P0340 error code is frequently triggered by a problem with the Camshaft Position Sensor itself. The following are the most often seen reasons:

  • Problem with the wire — The wiring for the Camshaft Position Sensor is subjected to more severe circumstances than a majority of the wiring in your Jeep. It’s worth taking a look at it to check whether it’s become too short, or if the harness connector has become loose or broken. You may learn how to detect an automobile short by reading this excellent article. Once you get the feel of it, it’s actually not that difficult to do. Failure of the camshaft position sensor – After thoroughly inspecting all of the wiring surrounding the CPS, it will be necessary to test the sensor itself. You may learn how to accomplish it using a multimeter by watching this amazing video.

P0340 can also be caused by a variety of factors that are substantially less likely.

These include the failure of the PCM or the failure of the Crank Sensor. In order to determine whether the voltage at the camshaft sensor is within specification, you must measure it.


P0340 is a significant issue that has to be handled as soon as feasible by the appropriate party. We recommend that you take your Jeep Wrangler to a repair as soon as possible after purchasing it. Feel free to leave a comment if you have any recommendations for how to make this post better. Thank you for reading. Wishing you the best of luck!

P0340 Jeep

A P0340 Jeep code indicates a malfunction in the Camshaft Position Sensor Circuit. If you believe this, you can conclude that you have an issue with the wiring to the camshaft position sensor. It’s possible that there’s a wiring issue. For those who have just just replaced the camshaft position sensor, there’s a good probability that you made a mistake with the air gap adjustment. It should have arrived with a green cardboard spacer on the tip of the sensor if it was a genuine Jeep sensor that you were installing.

  1. The spacer can be purchased from a retailer.
  2. The sensor should be installed appropriately by leaving the cardboard spacer on the tip of the sensor and butting it up against the cam reluctor.
  3. Once the engine is started, the cardboard spacer will be wiped away, and the gap will be adjusted to the proper setting.

  • Vehicle:2010 My 2010 3.8 continues to display the cam sensor code P0340, along with the traction control light illuminated and the vehicle in limp mode. I’ve cleaned the connections on the harness for the cam, the air sensor, and the coolant sensor, among other things. Apart from the tightness of the wiring and the exposed areas where the fragile plastic loom has dissolved, the wiring appears to be in good condition. This all began a day after I flushed the antifreeze and changed the oil on my car. However, the first code to be generated was P0116 coolant sensor. As a result, that as well as the thermostat were replaced. The P0340 code was shown along with the traction control light after the previous code was cleared. I can clear the code and restart the program, but it will immediately pop back up. It doesn’t start every time, as would be predicted if the cam sensor were to fail, but it does start occasionally. As a result, I haven’t changed it yet because I’ve watched so many folks just throw part after part at it with no success. I will, however, most likely order a new one the next day. I’ve combed the internet and discovered a slew of others who are in the same boat as me, but no solutions. I’m at a loss, and I was planning on taking it on vacation to the beach the next day for the next week. Right now, we’re driving in a Nissan Sentra, so you can understand how I’m feeling at the moment. Thank you in advance, gentlemen. I’m completely out of skills

Vehicle:2016 The p0340 code on a JK Wrangler Sport indicates a CIRCUIT problem, with the PCM failing to recognize the CMP signal. We find that investigating circuit difficulties is the most enjoyable and fascinating thing we do. I’m really trying to figure this out.

  • Vehicle:2010 Thank you so much for doing this. It may be necessary for me to find a garage or someone with a good scanner if this freshly fitted CPS fails to keep the dreaded codes at bay for an extended period of time. I just have a rudimentary one. I haven’t run the Jeep for more than an hour yet, which appears to be when the moment of truth will arrive. So far, the code has been eliminated. The guys who have had the same problem normally enjoy a well-running jeep for a day or two before the code and limp mode appear out of nowhere and they find themselves stranded on the side of the road. As a result, they end up concentrating on the fun and interesting wiring, which is what I’m going to do if this new CPS doesn’t solve it for them

  • Vehicle:2010 I was able to get the new CPS, which cost one hundred dollars, installed. But, I’m not holding my breath in hopes that this is the solution. However, have a look at the greasy dampness on the plug of the old CPS for confirmation. That is in no way how it should seem. I’m assuming that this suggests that it was simply a case of the CPS failing at an inconvenient moment rather than a wiring problem caused by me accidently tugging a wire loose in some way. Checking the wiring and spraying contact cleaner on the connection points were two things I performed.

It is possible that running with a new sensor and not performing the relearn procedure will result in the new sensor failing?!

code p0340 help and questions please!

A code P0340 might indicate that one or more of the following events have occurred: There might be a grounded, shorted, damaged, or flaky wire or connection in the circuit (first thing on the suspect list) *It is possible that the camshaft position sensor or the crankshaft position sensor has failed (or is just starting to fail) *It’s possible that the PCM failed (least likely, especially in your case with no symptoms) Here are some ideas to get you started: The camshaft position sensor should be tested, as well as the crankshaft position sensor.

*Visually verify all of the wiring and connectors in both of the circuits; repair as necessary; clean connectors using electrical contact cleaner- Assuming there are no symptoms (the extended crank is most likely due to a check valve on the fuel pump, which is unrelated), I’d start by clearing the code, detaching both cam sensors and crank sensors, and cleaning the contacts with a generous spray of electrical contact cleaner (widely available at any parts store; even Walmart) Reconnecting and checking to see if the CEL/code appears again.

It’s possible that there is a connectivity problem.
