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. In that vehicle the rust would build up in the fuel filter and when you went down hill it would completely block the filter resulting in fuel not getting to the engine.
When I took the filter off that old beast and blew it out I noticed the rust and realised what the issue was, drained and cleaned the tank properly painting the inside of it with a special rust treatment that was petrol proofreplaced the filter and never had a problem with it again. I get a feeling that the in tank filter in this beast is suffering from a similar clogging or like others have mentioned in that SCV thread, there's algae in the SCV causing a similar issue that's really only causing an issue when the vehicle is nose down.
If you're going through hell, keep going. Is there something else in there I have missed that you could point me to a bit more accurately than just the link? This will give you the large fuel leak code! Its quite common for the air to be leaking into the system before the filter, and then actually uses the filter housing as a little air damn, when you go down hill, it moves, allowing the air pocket to get sucked in the pipe leading to the pump.
Try this first, if it doesn't work, let us know and we can get on with helping you solve it. Thanks for the reminder to check for leaks in that area. I am at the stealer at the moment and they are just about to run the diagnostics. Driving to the Stealers this morning, no matter what I tried I couldn't get the mongrel thing to throw a fault code.
When I got there the guy said without a fault code it was going to be hard for him to pinpoint the problem despite me fully explaining what the symptoms where, what type of driving seemed to make it happen more frequently and supplying him the fault code that my ODB-II software on the phone had captured.By thestubeeFebruary 27, in Rav 4 Club.
Bought a year Rav4 XTR 2. Switch off and on again and everything fine again for a few minutes until is did it again. Plugged in my trusty code reader and the P code was stored indicating a large fuel leak. I should point out that I changed the fuel filter myself upon purchase as it was clear it had not been done - everything has been fine since the filter change. Anyway, after a large 'cough' the car appeared to clear itself and so I reset the codes.
Took it for a drive hard and all is good - problem solved, just a blip I thought. Next day, the same thing happened, this time also with a P code stored see attachement which indicated the MAP sensor may be at fault.
Main query is, where the hell is the MAP sensor? Also, anyone seen this condition before? Oh, should add that I took off the EGR valve and cleaned it at the same time as the fuel filter change.
Car is run on supermarket fuel but with Millers additive added P Is most likely caused by a faulty suction control valve, there is a technical service bulletin regarding this and a modified valve and ecu software update to fix. Thanks guys, is there a set of pictures somewhere for easy identification of the suction control valve and map sensors so i'm definately looking at the right things? I've never heard of an SCV giving trouble on a 4.
It is fitten inside the high pressure fuel pump. I'll find you some pictures when I get chance but I'm working funny hours for the next few days so remind me if it isn't done by Sunday. Im not high up on car mechanics but i think you have the same problem i had the efg valve is dirty.
The guys at Toyota removed and cleaned the valve and this fixed the problem for a week or so. They then replaced it and everything had been great since. Hope this helps. I've taken off all the vacuum pipework this morning and checked, all ok and free flowing with no splits leaks etc. I've also located the sensor on the front on the engine but the part code shows it to be the turbo vacuum sensor? Yet to take the car for a drive but she starts and rev's up OK after 2 mins priming the fuel pump again!!!
Egr stands for "exhaust gas regeneration" they get dirty quicker if your driving with low revs, so said the Toyota dealer P is the detection of a large fuel leak and is not related to EGR faults the reason you get lack of power is the car going into "limp" to protect the engine.
Looking at the read out you have posted P is the current fault and the other codes have occurred but are no longer present so they are stored in the memory's history.Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

So you should chech it on our car models. The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing.

This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver. Parts or components should not be replaced with reference to only a P DTC.

P0088 OBD-II Trouble Code: Fuel Rail/System Pressure - Too High
P code.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.
P is the OBD-II generic code indicating that the camshaft position sensor A for bank 2 does not correlate to the signal from the crankshaft position sensor. Note : Erratic drive complaints can happen depending on the failure and how long the vehicle is driven with the problems.
Clears the codes and then road tests the vehicle, simulating the freeze frame failure to duplicate conditions of when the last failure occurred. Turns the OCV on and off for the bank 2 camshaft and monitors the camshaft sensor for changes in the timing. Note : The manufacturer's tests may help to to narrow down the problem. Following these tests should help with your diagnosis without replacing the parts that are still good. Only parts directed by the pinpoint test or a visual check indicate what parts should be repaired or replaced.
The engine can have various drive problems like stalling or hesitations along with hard starting. The timing chain, tensioners, or guides may have problems that can lead to major internal engine damage if the valves hit the pistons. The camshafts being out of time may start to carbon the engine piston rings and valves, which can lead to the engine needing to be rebuilt for loss of compression.
Code P is the same as code P except for the opposite side of the motor.
If both codes are present then suspect the oil pressure is low or not getting to the OCV for both camshafts.

P0088 – Fuel rail/system pressure too high
Cost of diagnosing the P code. No more waiting rooms!By mnSeptember 5, in Auris Club. This is the first time posting on this forum so bare with me. I have been having quite a few issues with my Auris and could do with some advice. The first thing that happened was when I put my foot down in first and then changed to second the engine management light came on, the traction control light and check vsc.
The car then went into limp home mode so I turned the car off and then on again and the power returned but the lights stayed on. I cleared the code off and it only returns if I floor it in first and second. The other issue that is really annoying is when I try to start it it takes 3 - 4 attempts to start and then when driving it normally, it randomly cuts out on me and then takes a couple of attempts to start it again.
I have read a lot on this forum about the Suction Control Valve failing so think it might be this but just wanted some advice. Not an uncommon issue that is a result of fuel companies reducing sulphur content is fuel because of EU regulation, sulphur was a lubricant for components in the engine.
Think is why I have always used a lube with my diesel! Especially when using a supermarket one! Either using 2T Oil or millers or Archoil with our low sulphur derv These ULS fuels are great for the tree's! But lost most of the lube properties. I just like to use other additive with mine as I bought a load of Archoil AR stuff a while back and need to use it up You can post now and register later.

However, the range of ideal fuel pressures vary widely between vehicles, so consult the relevant manual to determine the correct range of pressures for the vehicle being worked on. The cut-away drawing below shows the typical construction of a fuel rail-mounted fuel pressure regulator.
There are not many causes of excessive fuel pressure. Since the fuel pump is running, it means that the problem usually does not involve electrical issues.
Some of the most common causes of high fuel pressure include the following. Wrongly installed fuel filters Note that if the fuel filter is installed the wrong way round, which is possible on some applications, there will be a high pressure condition only between the filter and the pump.
P0093 - Fuel System Leak Detected Large Leak
The pressure between the filter and the rail will be lower than normal or absent because the filter might not allow a reverse flow. Defective fuel pressure sensor Note that while a defective sensor could possibly set code P it is more likely to deactivate the pump than to cause a high fuel pressure condition.
In practice, it is more common for defective fuel pressure sensors to set low fuel pressure related codes. However, depending on the degree of deviation from defined fuel pressures, some, or all of the following symptoms may be present. NOTE: In severe cases, other codes that relate to emission control faults may be present, especially codes that relate to catalytic converter sand oxygen sensors.
NOTE 1: Apart from a repair manual, a dedicated fuel pressure gauge is required to accurately diagnose code P It is a common mistake to replace the fuel pump and other expensive components in attempts to remedy a no starting condition.
Code P indicates excessive fuel pressure, and the only way to determine the actual pressure is to test the pressure in the system with a proper fuel pressure gauge. NOTE 2: Many applications use a pressure sensor to continually monitor the pressure in the fuel system. This sensor must not be confused with the pressure regulator, which opens and closes in response to varying pressures to maintain the specified fuel pressure.
A defective pressure sensor could conceivably set code P on some applications, which is why it is important to physically check the actual pressure in the system with a pressure gauge. NOTE 3: If the vehicle is fitted with a fuel pressure sensor, consult the manual on the correct testing procedure. Defective pressure sensors can deactivate the fuel pump on some applications, so be sure to check the operation of this sensor in conjunction with the actual fuel pressure if the vehicle can start.
Begin the diagnostic procedure by recording all stored fault codes and available freeze frame data. This data can be useful if an intermittent fault is diagnosed later on. Sine code P indicates an excessive fuel pressure the problem is unlikely to be caused by wiring issues, unless the fuel pressure regulator is electrically operated. In some applications the pressure regulator is located on the fuel rail and operated by a spring with vacuum assistance obtained from the inlet manifold. Consult the manual to determine the location of the pressure regulator.Jeep 3.0L diesel CRD code p0088 prt1
NOTE 1: To ensure that the fuel pump is not being fed too high a current, perform reference, resistance, and continuity checks on all associated wiring. Repair all wiring found to be defective. Note that an excessive voltage is a rare occurrence, but perform all relevant tests to ensure that the pump is receiving the correct current, which is usually equal to the battery voltage. NOTE 2: Also perform a thorough inspection of all fuel lines, in particular the return line that delivers fuel from the fuel rail back to the tank.
