I need help, my truck is throwing the CEL. The code is
P0453 Evaporative Emission Control System Pressure Sensor High Input, I have the vent canister hooked up. The stock gas cap, and stock fuel pump o-ring. It is in a fuel cell now. I have a small connector, that comes off the main wire harness on the driver side frame by the rear of the cab. anyone know where this goes? The connector is square and gray. it is a 3-pin. the wire colors are purple?, red, and brown/white? i am thinking this is the problem. i need to know what it hooks up to. i have the connector that hooks up the the canister soleniod. any ideas that could be causing this? i talked to Ford, they wont work on my truck cause the fuel cell. sucks...
they said it could be a connector not plugged, the fuel cell itself, a purge valve, or the fuel canister vapor soleniod.
Please help, emissions due yesterday!
-oh when i moved the fuel canister, i had to cut the wires on the connector, would that make it bad? i figure when the code says "Pressure Sensor High Input" that could mean too much voltage??? i dunno
