A fuel pressure sensor mounted on the common rail assembly converts the fuel pressure inside the common rail assembly into an electric signal, and outputs it to the ECM. The ECM controls the supply pump assembly in order to maintain the fuel pressure inside the common rail assembly at a target pressure calculated by the ECM.

For more information on the common rail system, refer to System Description. If the drop in the internal fuel pressure is large when injection fuel, the ECM interprets this as a fault and stores P This DTC indicates that fuel leaks exist in high pressure areas in the common rail system.

The ECM constantly monitors the internal fuel pressure of the common rail assembly after the engine is started. In the common rail system, high pressure fuel is always supplied to the high pressure areas including the supply pump assembly, common rail assembly, injector assemblies and piping. The ECM adjusts the suction control valve opening angle to obtain the target internal fuel pressure. The fail-safe mode suspends both fuel injection and supply pump operation, and then stops the engine.

Before stopping the engine, the ECM permits the vehicle to be driven for 60 seconds. The fail-safe mode continues until the ignition switch is turned off. Rev the engine to rpm and fully release the accelerator pedal immediately after the engine reaches rpm. Soon after starting the engine, visually check for fuel leaks in the fuel line. Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected.

When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, and other data from the time the malfunction occurred.

The common rail fuel pressure dropped suddenly when the engine was being run at a moderate engine speed during engine warmup and DTC P was stored at the point when data set 4 was recorded. Injection Feedback Val 3 is 5. Actual cause: In this case, foreign matter in the fuel is stuck inside an injector causing the injector to malfunction temporarily.

In order to remove the foreign matter in the fuel the major cause of the problemthe fuel filter case needs to be cleaned and the fuel filter needs to be replaced. This can be seen clearly by comparing it to Target Common Rail Pressure. Before starting the engine, visually check for fuel leaks from the supply pump assembly, injector assemblies, common rail assembly and the fuel pipes in high pressure areas.

Using the hand pump mounted on the fuel filter cap, bleed the air from the fuel system. Continue pumping until the pump resistance increases. When the fuel pressure at the supply pump inlet port reaches a saturated pressure, the hand pump resistance increases. If pumping is interrupted during the air bleeding process, fuel in the fuel line may return to the fuel tank.

Continue pumping until the hand pump resistance increases. If the hand pump resistance does not increase despite consecutively pumping times or more, there may be a fuel leak between the fuel tank and fuel filter element sub-assembly, the hand pump may be malfunctioning, or the vehicle may have run out of fuel. If a large amount of air remains inside the fuel system, the common rail pressure does not rise to the pressure range necessary for normal use, and the engine cannot be started.

If a large amount of air remains inside the fuel system, the starter may need to be cranked for 10 seconds or more to start the engine. Do not crank the engine continuously for more than 20 seconds. The battery may be discharged.

If the engine cannot be started, bleed the air again using the hand pump until the hand pump resistance increases. Then start the engine. Allow the engine to idle for 3 minutes or more after performing the Active Test for the 5 times [D].

Confirm that the shift lever is in neutral and securely apply the parking brake.This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. A code exists for a large leak, small leak, and very small leak. There is a range of fuel leakage programmed into the Powertrain Control Module PCM by the manufacturer to determine which code will be stored based on the amount of leakage.

The mechanic will start by visually inspecting the fuel system, searching primarily for the leak.

Since the leak is considered a large leak, it should be fairly easy to locate. Once the source of the fuel leak has been found, the mechanic will repair or replace the part that is causing the large fuel leak.

Considering that the issue at hand is a large fuel leak, it would be quite difficult to make a mistake during diagnosis. This issue is as simple as locating the fuel leak and having it repaired. The P code is very serious. Having this code stored in your Powertrain Control Module can be a safety issue.

With this code in the system, it is a safety hazard because a fire can be caused by this. It is very important to have the fuel leak located and repaired as soon as possible. Any part of the fuel system can cause this code.

Number of Reviews 5,New Subscription Renew Subscription. P Error Code Petrol, gas, fuel tanks etc. I have done forum searches for P but they all seem to refer to problems with aftermarket chips and this vehicle doesn't have one fitted. Unlike some of the posts I read in the search results, the error does not happen under acceleration. The error occurs almost everytime when going down hill with the foot off the accelerator or when I am stopped at the lights in and the front of the car is facing down hill.

There are no obvious fuel leaks anywhere, it just splutters and conks out. The car will start immediately after but if I take my foot off the accelerator again on the next downhill slope or stop again at another set of lights facing down hill, it happens again.

I've changed the fuel filter under the bonnet and bled the fuel system, I've put injector cleaner in the tank a few times and its still happening. I've filled up at a number of different service stations over the past month or so and its had quite a bit of fresh fuel through the system so it doesn't appear to be contaminated fuel.

Its like its starving for fuel but only when the nose of the car is facing down hill. I read in a number of internet posts that most problems are not injector or main diesel pump related but can often by a blocked filter in the tank, damaged in tank pump or blocked in tank pickup screen however the dealer will always try to get you to replace all injectors and the main diesel pump before they try anything else. That's a very expensive option from what I hear so I don't want to do that unless all other possible issues have been ruled out first.

Its been driving me crazy so I have made an appointment with the dealer to get it checked tomorrow, does anyone have any ideas before I go to the dealer tomorrow.

Thanks in advance, Ash. Build thread: viewtopic. In the other posts that mentioned the stepper motor in the turbo, they usually saw other faults in addition to the P, I am only receiving P powertrain - major fuel leak. Would there be any other symptoms if it was a stepper motor in the turbo other than it cutting out? Currently I have no loss of power at all, just this stalling symptom going downhill. Sometimes it sucks getting passed by a hilux, I don't seem to have that problem though.

Just trying to help mate. When I was reading the SCV cleaning thread I thought it might be on the right track because as the understanding I came to was that the SCV controls the suction of fuel from the tank and the engine certainly appears to be suffering from starvation of fuel when the foots off the throttle.

What made me think it mightn't be the problem though was when I read the bit about the surging that's usually experienced when this is the cause. The symptom I have is a bit like what used to happen in an old petrol engine I had years ago that had rust in the fuel tank.DaviesApril 4, in Rav 4 Club.

After changing the fuel filter, priming it button on top of fuel filterthe car starts after 10 seconds. Primed it a number of times but it is still difficult to start and when driving is a bit hesitant. Any ideas on how to bleed the system? Did you renew the seal and is the filter fully tightened because it sounds like air may be getting in the system. You must bleed the system before the engine runs right. Keep pressing that plunger on top until it goes hard and then start it. If you still have problems, take the out pipe off and pump it until the fuel runs.

Reconnect the pipe and pump it until it goes hard then start it. You can expect it to splutter for 5 or 10 seconds but if it still causes problems you have done something wrong.

Take the filter off again and check the seals are not twisted or you haven't fitted 2 seals in error at the top. Lightly Oil them with engine Oil and refit then re bleed. I've learnt this from our generator running out of diesel; the Renault 7 ton truck; and the forklift. With petrol, you just fill up the tank and away you go. Diesel has to be primed; pumped; connections loosened to let out air. You can post now and register later. If you have an account, sign in now to post with your account.

Running out of fuel at a very fast rate Extremely poor fuel economy The risk of a fire Fuel pressure decrease could cause the engine to run poorly, further decreasing fuel economy How does a mechanic diagnose the P code? Common mistakes when diagnosing the P code. How serious is the P code? What repairs can fix the P code? Some of the parts that could be replaced to repair this issue would include: Replacing the fuel tank Replacing the fuel lines Replacing the fuel hoses Replacing the fuel injectors Replacing the fuel rail Replacing the fuel pressure regulator Additional comments regarding the P code.The Toyota KD engine series is a diesel engine produced by Toyota which appeared in It has 16 valves and a double overhead camshaft DOHC design.

Compression ratio is This is combined with a bit ECU which controls fuel quantity, valve timingand boost pressure at different engine parameters resulting in best fuel economy and also full utilization of power during acceleration.

Pilot injection is also utilized by the common rail fuel system to smooth engine operation. Small amounts of fuel are introduced into the combustion chamber prior to the main injection event, reducing lag time and promoting more continuous and complete combustion.

Exterior and interior engine noise is also reduced.
