2006 Pontiac Grand Prix Fuel Pressure Sensor.
Trying to clear a check engine. And it wasn't the
fuel cap so I know it is this sensor. I have looked
up so many videos and forums and talked to
people and it seems 2005 and prior had a trap
door. I have pulled the carpet, and seat and can't
find one. Am I seriously going to have to drop the
tank for this stupid little sensor? Please someone
tell me a quicker way!!!
There's no quicker way: yes, you need to drop the tank
What trouble code do you have? -Jim
I believe it was 440... I can't remember now. It is for fuel tank pressure. I tried replacing the gas cap and it did not fix it. It isn't hurting anything other than I can not use auto start because of the check light.
I see. A P0440 trouble code is for the EVAP system but it could be any number of things. Best to let a pro smoke test the system so you don't wind up just throwing parts at it and spending more money then you need to. HTH. -Jim
had the same problem access to fuel gauge assy. is behind the passenger side back seat....check the sensor under the drivers side backseat under the car
