My cel came on the other day and it threw the code p0452 at me. I'm assuming its either the fuel pressure sensor or my fuel pump. Has anyone come across this problem before?
Fuel Pressure Sensor?

"P0452 Evaporative emission control system pressure sensor low input"
It has to do with the fuel tank pressure. Its most likely a loose gas cap, faulty gas cap, or rusty fuel filler tube.

P0452 means the sensor output is low .... meaning the sensor is defective ( open ) OR you have a broken wire/bad connection between the ECU and the sensor in the tank.
This error does not point to the actual pressure in the tank being low. but the circuit from the ECU to the Pressure sensor and the return back to the ECU.

so if the output is low could it be the sensor itself?
Yes as I stated above, the sensor or any wiring or connectors back to the ECU can cause this code.
ok cool. Thanks for the help
so i went to auto zone and they gave me a read out of what it could be and it said that it could be the evap sensor. is that the same as the fuel tank pressure sensnor? and where is it located?
The sensor, if I'm looking at this correctly is about in the middle of the top of the fuel tank. Looks like you may have to drop the tank to get to it.
i know its within 6 inches of the pump. im hoping theres an access panel. haha. im gonna attempt it wednesday.
There are 2 access panels in the back, I believe the sensor is right between the 2.
alright. so i pulled a sensor from a junk car today for 10 instead of 400.... but its nasty as hell in spokane so im wainting till tomorrow to put it in. any advice?
