Hello and Welcome to Justanswer, My name is XXXXX XXXXX I am here to try and assist your with your question
you need to moinitor the fuel rail sensor pid against the acuall fuel pressure
If it is off the fuel rail pressure sensor is bad.
I did this and both were in agreement in that the pressure was within the nominal 39 psi. One time I caught the fuel rail pressure sensor reading 54 psi, but by the time that I got the gauge on it it was back to nominal
have seen fuel rail pressure sensor go bad
I would start with the sensor
this is on the fuel rail
Is this just a sensor or is it a symptom of pressure issues somewhere else?
The reason I ask is that the car does jerk now and then and that is when the engine light goes on and the code is P0191
The computer controls the fuel pressure with the fuel rail pressure sensor. If it is giving false readings to the computer then the fuel pressure will be off and cause concerns
Excellent. Then I will replace the sensor. I noticed that it rather pricey! Is there a solenoid as well with it or just a sensor or is it a single package if you will?
It is just a sensor
get one piece for a expensive price
OK! I will give it a try and hope that this is the cuprit. Thanks for the information. Appreciate it!
