EVAP canister vent control valve open code P1448 where do you find this valve and how do you diagnose it?
on most gm cars its on top of the engine. to diagnose you have to pull a vac or pressure it... a bad gas cap can give the same fault
It is probably not the fuel canister itself that is leaking.......on the back side of the canister ther is a small plastic drain valve.....this valve has an O-ring in it that dries up and fails causing the leak. the drain valve has a yellow valve control on it. It is a very cheap part and easy to fix.............Nick
What part do you ask for when your '96 3 liter Aerostar's check engine light comes on and a code reader displays:P1443 meaning evaporative emissions control valve?
The Evaporative Emission Control System monitors the fuel vapor flow between the engine intake manifold and the EVAP canister. The system failure occurs when a leak or blockage between the intake manifold, the EVAP canister purge valve and the EVAP canister is detected by the PCM. Code P1443 Possible Causes: - Pinched, blocked or plugged fuel vapor tubes/hoses (except between fuel tank and EVAP canister) - Damaged EVAP canister - Disconnected, cracked or cut fuel…
The canister vent valve is located in back close to the fuel tank. The canister purge valve is located up front on the engine. If you're looking for the purge valve, look for a black plastic vacuum line under the hood that has a green dust cap on it. Follow that black line back to the engine. It will be connected to the purge valve.
