Want this question answered?
P0449 indicates a problem with the the EVAP vent valve solenoid circuit. Could be the valve or wiring. good-day !
P0443 - EVAP control system CANISTER PURGE VALVE CIRCUIT MALFUNCTION - VPWR circuit open - Evap canister purge valve circuit shorted to ground - damaged EVAP canister purge valve - EVAP canister purge valve circuit open - EVAP canister purge valve circuit shorted to VPWR - damaged PCM
p1446
P1148
the 4308 code is for a evap system leak. this could be caused by many different components including the filler neck, evap lines, evap purge valve, vent control valve or even a loose or bad gas cap.
underneath the rear of the vehicle near the spare tire if i remember right. it is on the side of a black box (evap canister) it is the "vent control valve". it could be other things than just the valve itself setting this code.
Hi, To fix a po449 on a Chevrolet Venture will take a little troubleshooting, and probably a "scan tool" that is actually capable of sending commands to the control computer. This is because you have to "listen & feel" around the EVAP module while telling it to open & close this solenoid. I have provided a link that has more details about this code. Good Luck, Greg
i think the code p1400 means exhaust gas recirculation(EGR) system/ evaporative emission(EVAP)system- valve mulfunction i think the code p1400 means exhaust gas recirculation(EGR) system/ evaporative emission(EVAP)system- valve mulfunction i think the code p1400 means exhaust gas recirculation(EGR) system/ evaporative emission(EVAP)system- valve mulfunction
The evap control valve is on the cannister
evap canister purge control valve circuit fault
Low purge flow- faultu evap valve or canister.
Trouble code P1446 means: EVAP Canister Vent Valve Malfunction (Closed)
