SYMPTOM
P0443 - 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.

POSSIBLE CAUSES
- Fused ignition switch output circuit open
- Proportional EVAP purge solenoid defective
- EVAP purge solenoid circuit wiring harness intermittent defect
- EVAP Purge solenoid circuit wiring harness observable defect
- EVAP purge solenoid control circuit open
- EVAP purge solenoid control circuit short to ground
- Proportional purge solenoid control circuit short to ground
- Proportional purge solenoid control circuit open
- PWM purge sense circuit open
- PWM purge sense circuit short to ground
- Powertrain control module defective
