P0443 EVAP Purge Solenoid Circuit
SYMPTOMP-0443 EVAP PURGE SOLENOID CIRCUIT
WHEN MONITORED
At ignition key on and battery voltage greater than 10.4 volts.
SET CONDITION
After arming conditions are satisfied: not power down, not already in limp-in, time since last solenoid activation > 72 micro seconds. The powertrain control module will set a trouble code if actual state of the solenoid does not match the intended state.
POSSIBLE CAUSES
- Fused ignition switch output circuit open
- Evaporative purge solenoid defective
- EVAP purge sol ckt wrg harness intermittent defect
- EVAP purge sol ckt wrg harness observable defect
- EVAP purge solenoid control circuit open
- EVAP purge solenoid ctrl circuit shorted to ground
- Powertrain control module defective
