SYMPTOM
P0443 - EVAP PURGE SOLENOID CIRCUIT

WHEN MONITORED
At ignition key ON and battery voltage greater than 10.4 volts (during initialization or power-up).

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

POSSIBLE CAUSES
- Fused ignition switch output circuit open
- Evaporative purge solenoid
- EVAP purge solenoid circuit wiring harness & connector intermittent defect
- EVAP purge solenoid circuit wiring harness & connector observable defect
- EVAP purge solenoid control circuit shorted to ground
- Evaporative purge solenoid control circuit open
- Powertrain Control Module
