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. It may need nothing more than a good cleaning, vacuum hose connected or that is leaking, or may need more. I suggest you seek out the services of a good mechanic. Do not just throw parts at this. The code does not mean that any part needs replacing. It just means the EVAP system is being effected.
