P0443 code, EVAP system control purge control valve circuit
failure, p0441 is related to p0443. if you fix it, both codes should be gone! to fix p0443-- Using a scan tool, command the purge solenoid to activate. Listen or feel for a clicking coming from the purge solenoid, If it doesn't click with scan tool
activation,
unplug the connector and examing the solenoid and connector for damage, water,
etc. Then check for battery voltage on the feed wire with the key on. If you
have battery voltage, then ground the control side manually using a jumper wire
and see if the valve clicks. If it does, then you know the solenoid is working
properly but there is a problem with the control circuit. If it doesn't click
when you manually ground it, replace the purge solenoid.
