P1212 & P1211 are ICP errors. Try unplugging the ICP sensor (in the front of the Left Head, up top) the PCM will default to a limp setting if it gets no reading from that sensor and, if your ICP is bad, it will probably start.
- Fix code P1211 P1212 Ford Powerstroke Diesel Ford Diesels use oil pressure to drive the high pressure fuel injection system. The engine oil pump not only pumps oil to lubricate engine components, but also pumps oil into a reservoir to be used by the high pressure oil pump.
What is a P1211 code 7.3 Powerstroke?
OBD-II Code P1211 from a 7.3 Liter Power Stroke is often caused by running “Hot Chips” or tunes that are demanding more ICP (Injection Control Pressure) than the HPOP (High Pressure Oil Pump) can deliver and can be accompanied by a lack of power or rough running.
How much fuel pressure does a 7.3 Powerstroke have?
40 – 70 psi at idle is within spec. You may notice rapid fluctuations in the fuel pressure reading; this is completely normal for the mechanical fuel pump found on 1994.5 – 1998 model year engines. So long as the minimum pressure reading is greater than 40 psi, the fuel pressure is within spec.
What was the last year Ford used the 7.3 diesel?
2003. 2003 was the last year of the 7.3L Powerstroke engine being used in Ford Superduty Trucks.
What causes a 7.3 to lose power?
Clogged fuel filter. A restricted fuel filter will often cause long cranking or a semi-loss of power, if the injectors can’t get the fuel they need. Replace fuel filter.
What problems does the 7.3 Powerstroke have?
Some of the most common 7.3 Powerstroke engine issues include: Turbocharger Up-Pipe Leaks Have Become Significantly Common. The Diesel Fuel Filter Can End Up Becoming Clogged. Failure Of The Injector Pressure Regulator Is Something To Worry About.
Where is the fuel pump on a 7.3 Diesel?
The fuel pump on all 7.3L Power Strokes is located in the engine valley just in front of the turbocharger.
Does a 7.3 Powerstroke have an injection pump?
A Bosch high-pressure oil pump (shown) graces the 7.3L Power Stroke. The injection pressure regulator (controlled by the PCM) is responsible for creating injection pressures in a range of 450 to 3,000 psi on 7.3L engines, and 450 to 3,600 psi on 6.0L Power Strokes.
How many fuel filters does a 2001 7.3 Powerstroke have?
How to Replace Fuel Filter on a 7.3L Power Stroke. The 7.3L Power Stroke has a single fuel filter located near the front of the engine in the valley. It features a convenient drain valve and tube system that allows the housing to be drained remotely.
What powerstroke to avoid?
The 2003-2007 Ford Super Duty 6.0L may be the worst diesel truck of all time. The 6.0L Powerstroke is infamous. The engine is so bad that Ford and Powerstroke parent company Navistar were engaged in a serious legal battle.
Is 6.0 or 7.3 Powerstroke better?
From a reliability, durability or simplicity standpoint, the 7.3L is hands down the winner. When it comes to horsepower, drivability and meeting modern day emissions standards, the 6.0L has it beat. Ultimately, both engines have their pros and cons.
P1211 P1212 Ford Powerstroke Diesel
The high pressure fuel injection system in Ford Diesels is driven by the oil pressure generated by the engine. While the engine oil pump is responsible for lubricating engine components, it is also responsible for pumping oil into a reservoir that will be utilized by the high-pressure oil pump. The high pressure oil pump draws oil from the reservoir and boosts the pressure to a level that allows the injectors to be opened by the high pressure oil pump. As a bonus, the high-pressure pump raises the pressure of the diesel fuel, making it easier for it to enter the combustion chamber and evaporate fast.
With each power up and power down cycle of this Injection Pressure Regulator (IPR) solenoid, a tiny shaft rotates back and forth, enabling spurts of oil to flow into the high pressure oil lines.
Stainless steel braided lines transport high-pressure oil from the pump to the cylinder head.
In contrast to gas fuel injectors, in which the solenoid lifts a pintle off a seat to allow pressured gasoline to flow into the cylinder, the solenoid in Ford diesel fuel injectors allows high pressure oil to flow through the injectors.
- Pressurized oil acts as a spring, pushing on the plunger of the syringe, causing the fuel to be ‘injected’ into the cylinder through the injector.
- The PCM may adapt the pulse rate to the IPR based on the data from the ICP sensor and the IPR.
- However, it is the responsibility of the IPR to limit the amount of pressure applied to the injectors.
- Despite this, the PCM is capable of producing an IPR with a duty cycle of up to 60 percent.
- If you receive this code, the first thing you should do is check the level of oil in the crankcase.
- While the oil pressure sending device on a gasoline engine is positioned in the engine block, within a gallery, the oil pressure sending unit on a Ford Diesel engine is located at the top of its high pressure oil reservoir.
- If the oil ‘idiot’ light does not illuminate, it means that the high pressure oil reservoir is not receiving sufficient pressure.
If the oil level is correct and the oil pressure light is not on, proceed to the next set of inspections.
When the PCM detects that the RPMs have reached 150, the IPR is activated and the oil pressure is regulated.
As previously stated, the PCM has the ability to dictate an IPR duty cycle of up to 60 percent of the time.
It is reasonable to assume a malfunctioning ICP sensor if the ICP scan tool output indicates 2,000-2,500psi and the engine is not operating at the time.
If the high pressure pump is not operating, the IPR is defective, or there is a big leak anywhere in the system, pressure increase will be prevented until the problem is resolved.
Afterwards, disconnect the high pressure line from the left-side cylinder head and attach a high-pressure gauge (3,000psi or above) to the line.
The problem is either a malfunctioning high-pressure pump or a bad inlet pressure regulator (IPR) if the reading is low.
First and foremost, you must replace the IPR. If the problem persists, it is necessary to replace the high-pressure pump. Rick Muscoplat was born in the year 2012. Rick Muscoplat posted a blog entry on
P1211 and P1212
On March 6, 2008, at 3:58 p.m. PostmasterThread StarterJoined the forum in January of 2005. Brandon, Manitoba is the location. Posts: 4,127Likes: 0Received 1 Likeon1 Posts: 4,127Likes: 0 Post P1211 and P1212 are two of the most common digits in the English language. These are the two codes that I received after completing my stage 1 tests. ICP is not controlled since the pressure is higher than desired (1211) and the ICP voltage is not at the appropriate level (1212). Are these issues related to HPOP pressure or to actual fuel pressure?

I was just looking for confirmation.
Those stage 1’s are more than sufficient!
I suppose I’ll have to start putting money aside for a 17-degree HPOP.

Power Stroke OBD-II Fault Code P1211
Strike with great force ICP is higher or lower than desired, according to OBD-II code P1211 (7.3L) A 7.3 Liter Power Stroke with OBD-II Code P1211 is frequently caused by running ‘Hot Chips’ or tunes that require more ICP (Injection Control Pressure) than the HPOP (High Pressure Oil Pump) can give. This is followed by a lack of power or rough running, and it can be difficult to diagnose. For what it’s worth, the following are the precise arguments that cause this code to be executed: For 7 seconds, the ICP was 410psi higher than desired.
It is possible that code P1211 is triggered by a valid High Pressure Oil System malfunction.
- The IPR (Injection Pressure Regulator) has failed or is stuck
- The high pressure oil pump has failed or is weak
- Any leak in the high pressure oil system (o-ring, stuck injector, etc.)
- And low fuel pressure (rare). P1280 / P1281 / P1283 – (7.3L)
- P1280 / P1281 / P1283 – (7.3L)
The codes listed above are also associated with ICP. If the SES (Service Engine Soon) light is illuminated and these codes are present, the ICP measurement obtained using any scantool will not be correct since the PCM is utilizing a ‘default’ ICP value, which is determined by the manufacturer. All of these codes have a ‘electrical’ component to them. Shorts between the Red and White IPR wires, as well as between the Red IPR wire and ground, are common reasons of IPR failure. These can also be an indication of a PCM issue in rare cases.
The IPR Valve manages the oil bypass circuit of the high pressure oil pump. It is also known as the bypass valve. A high-pressure oil injector is controlled by an electromagnetic valve that opens and shuts in response to the pressure of the oil. This enables the PCM to manage fuel supply by adjusting the speed at which the IPR valve opens, making it a vital component in your vehicle’s overall system operation. The IPR valve in your car may be malfunctioning if you are having no or difficult starting when the engine is hot or after stalling, yet the engine starts normally when the engine is cold, or if your vehicle is idling abruptly or jerking.
- Direct replacement of the Injector Pressure Regulator Valve fails when there is no start, abnormally idling or jerking, cracks, or quits operating of the fuel injector pressure regulator valve.

- 6.0L V8 Diesel Engine with Turbocharger Ford F-550 Super Duty models from 2003 to 2010.
- Internal valves, diaphragms, and springs that are precisely produced ensure that you will have a reasonably dependable IPR valve that will operate wonderfully under all engine running situations and will appropriately manage the pressure in the high-pressure oil system.
