I have service engine codes p1448,p1800, p0444 and p0455. I replaced the caniater and vent valve with junkyard parts and tested the purge valve (that is working fine no leaks). When i checked the codes before i replaced the parts the p0444 wasnt there. Could this be the sensor? Anyone else have these codes, if so what did you replace? I dont want to dump money on parts i dont need..

P0444 & P0445 - EVAP canister purge volume control solenoid valve

P1448 - EVAP canister vent control valve

P1800 - VIAS control solenoid valve

The EVAP canister vent control valve is bolted on to the charcoal EVAP canister behind the left rear wheel. I think you are trying to say you replaced this and if you did, you got a bad part.

The EVAP canister purge volume control solenoid valve and the VIAS control solenoid valve are under the hood, bolted to the engine's intake manifold.

See page 24 in the link below for the location of these parts.

In the index at the front of the document, look up the Pxxx code and read more info about it, such as how to test the part.
