SYMPTOM
P-0443 EVAP PURGE SOLENOID CIRCUIT

WHEN MONITORED
With the ignition key on and the engine running.

SET CONDITION
After arming conditions are satisfied: not powering down, not already in limp-in, time since last solenoid activation> 72 micro seconds. The PCM will set a trouble code if the actual sate of the solenoid does not match the intended state.
