[QUOTE="NewOrleans-YAT, post: 16169834, member: 86027"] I am getting this code Could it be related? Also what should i change first to remedy this code. Also the fuel tank grommet is torn and leaking. I read that this can affect the EVAP system as well. I am changing the grommet next P0443 - EVAP Control System Canister Purge Valve Circuit Malfunction The PCM monitors the state of the EVAP canister purge valve circuit output driver. The test fails when the signal moves outside the minimum or maximum limit for the commanded state. VPWR circuit open EVAP canister purge valve circuit shorted to GND Damaged EVAP canister purge valve EVAP canister purge valve circuit open EVAP canister purge valve circuit shorted to VPWR Damaged PCM To verify normal function, monitor the EVAP canister purge valve signal PID EVAPPDC (or EVMV for electronic valve) and the signal voltage (PCM control side). With the valve closed, EVAPPDC will indicate 0% duty cycle (0 mA for EVMV) and the voltage approximately equal to battery voltage. When the valve is commanded fully open, EVAPPDC will indicate 100% duty cycle (1000 mA for EVMV) and a voltage drop of 3 volts minimum is normal. Output test mode may be used to switch output ON/OFF to verify function. [/QUOTE]
