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
Not powering down, not in limp-in and time since last solenoid activation is greater than 72 micro seconds. The 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
- Wiring harness intermittent problem
- EVAP purge solenoid control circuit open
- EVAP purge solenoid control circuit shorted to ground
- EVAP purge solenoid
- Powertrain Control Module
