I had a Big O mechanic point at out where the EVAP purge canister was.
Diagnostic Trouble Code (DTC) P1443 indicates a failure in the EVAP canister purge valve circuit. The Evaporative Emissions (EVAP) Canister Purge (CP) valve controls the flow of vapors from the fuel vapor storage canister to the intake manifold during various engine operating modes.
The canister purge valve is located at the LH front of the engine compartment, below the air cleaner assembly.
