Diagnosis Procedure
- CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR FOR WATER
- Disconnect EVAP control system pressure sensor harness connector.
- Check that water is not inside connectors.
Is the inspection result normal?
YES: GO TO 2.
NO: Repair or replace harness connector.
- CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR POWER SUPPLY
- Turn ignition switch ON.
- Check the voltage between EVAP control system pressure sensor harness connector and ground.
