By andymcOctober 19, in General Dealer Chat. Fuel rail pressure sensor is it 1. Done one on a Focus. You need a big socket to go over the sensor. If they are sure and you're happy to cough up what they're asking money wise do a 'full and final settlement' email. You can't be responsible for more cost in the event of poor diagnosis! I was going to say this when I first read your post but thought it was too obvious because there would have been a oil mess nearby.

Bonjour Leluxuriant, Merci pour ta venue et pour l'aide que tu pourras apporter. A vrai dire je n'ai pas dit grand chose au garagiste chez qui la voiture est actuellement.
Il voulait bien le faire en pensant que ce serait simple.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.
The power control module PCM has detected that the fuel pressure is not within the normal range which is required for proper engine operation. The mechanic will inspect the fuel rail pressure sensor wiring and connectors.
They will check for wires that are burned or shorted and connectors that are corroded. If necessary, replace the connectors and circuitry.
There could be an intermittent problem if the trouble code P does not return immediately. It may not be possible to diagnose an intermittent problem right away. They will then test the fuel pressure with a fuel pressure gauge. A low fuel pressure reading could be an indication that the vehicle is out of gas. It is important to make sure there is gas in the car during this step in the diagnosis process.
After confirming that there is gas in the car, make sure the fuel pump is operating by listening to it. If they cannot hear the fuel pump, they will tap on the fuel tank while simultaneously attempting to start the car.
This step will require two people. If the car does not start, the battery voltage will need to be checked at the fuel pump connector. If there is no battery voltage reading at the fuel pump connector, the fuse circuit, fuel pump relay circuit, and power control module PCM circuit should be inspected.
If the fuse, fuel pump relay, and power control module PCM circuits are not working properly, inspect the fuel rail pressure sensor. Test the fuel rail pressure sensor for a reference voltage at the connector with a digital volt ohmmeter.
A good reference voltage reading is 5-volts and this should be tested when the car is running. If the fuel rail pressure sensor has a 5-volt reading, the next step would be to test the sensor ground wire.Intermittent faults are the bane of our lives in the garage and often a fault can happen before your eyes, but might pass without a chance to spot the glitch on your scan-tool or to take a measurement with your multimeter.
Even an oscilloscope can miss a glitch, so it is important to use a setup that is most likely to capture the moment a problem occurs. Recently though we were fortunate to have the scope set up whilst a problematic Peugeot faltered before our eyes, thankfully the scope was gathering data.
This Peugeot 2. We initially started off by plugging the scan-tool in and noting the following fault codes:. P Fuel rail pressure signal coherence. There is no simple answer here and your approach will probably depend on the ease of access to the associated components. A physical injector leak off test might be a first step, but on the other hand if the injectors are buried deep and the rail pressure sensor is easier to access then that might be the focus of your efforts.
Historically the technician has been restricted to some degree when using a scope, by the limitations of sample rate over longer time bases, which would mean that the finer detail needed for close scrutiny would be lost. In the past, the best way of capturing fast events, would be with a short collection time and this would have been considered an adequate method.

These days though we are spoiled somewhat with the immense detail that Picoscope can capture, for the past few years we have had the opportunity to capture impressive detail, with massive amounts of screen time in comparison to older models and the majority of alternative automotive scopes. Anyway, back to the patient. This vehicle would occasionally display the fault at idle and with no driver intervention.
By studying the duty cycle and current flow of the pressure control solenoid at the same time, then maybe a clue to the fault might be uncovered. Following on from my previous comments about larger screen time bases, here is a capture that demonstrates the point very well. It gives us a greater perspective of what is happening and things can often take on a greater significance when looked at this way.

Here we are looking at the fuel pressure control. With fifty seconds per screen, there is a greater chance of seeing any significant shifts in the current flow and sure enough we can see exactly that, just that toward the end of the capture as the red trace rises. In days gone by, we would be restricted to the view that we see when the waveform is zoomed to a very high level, as seen in the following animation:.
Just imagine how quickly, an event would have flashed up on screen and then disappeared into the buffer if you had that luxury or possibly lost forever.
Many technicians will study either duty cycle or current flow, when looking at actuators, yet there is such value in looking with both duty and current traces combined.
This capture from the pressure control solenoid highlights the point nicely. We are able to see both the command and demand relationships of the component, zooming into the detail we can see that whilst the current flow through the solenoid has increased dramatically, there has been no corresponding increase in command, witnessed in the duty cycle signal.
The conclusion drawn from this waveform, is that the fuel pressure regulator solenoid, through a partial internal failure has demanded more current from the circuit.
Replacing the component fix the issues with the vehicle. Imagine the variety of conclusions that you could come to, if you had limited yourself to looking singularly at duty cycle or current and then being further limited to a small time capture. Don't restrict yourself with poor and outdated equipment and the practices that went hand in hand with it.

Your gas mileage will also be terrible, so you should try and fix it as soon as you can. 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. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.

You're looking for a sticking or stuck VCt solenoid valve caused by contamination.
Refer to vehicle specific repair manual to perform component tests for the VCT unit. Remove the air filter box assembly so you can access the transmission range switch. Turn the key to the ON position, but do not start the vehicle. Move the shifter to the neutral position. Align the alignment holes between the switch and the shift lever. Insert a 5mm drill bit into the adjustment hole to verify the proper alignment for the neutral position. The P Peugeot check engine lamp is perhaps the most troubling of lights because it could mean so many different things, from you didn't screw the gas cap on tightly enough to look out for pistons flying through the hood and into the stratosphere.
