P0443

Hi All, I got this code and I would appreciate it if someone can tell me where is best to look. Thank you

P0443 - Evaporative Emission Control System Purge Control Valve Circuit

sounds like the purge valve is not working. or short in wires. might be able to help with a location if you tell me the year of car.

your profile shows your car is a 01 impala. The purge control valve/solenoid is located in the following locations:

3.8 vin-K= just in front of upper plenum, slightly toward passenger side
3.4 vin-E= just behind throttle body on drivers side of upper plenum

check the wiring for loose/dirty/corroded connections and hard plastic vacuum lines for cracks/burnt areas/obvious problems before replacing the valve itself.

I agree it sounds like a flaky purge solenoid.

The DTC is a Cannister Purge Solenoid Circuit Fault, meaning electrical related. The P0443 DTC sets because the output driver has failed the electrical integrity check. The output state is invalid. Always a good idea to troubleshoot the problem first before replacing parts.

I believe the poster has a SII 3800.

It's the 3.8 and I'll try changing it. Thank you
