Diagnosis Procedure
1.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR FOR WATER
Water should not exist.
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace harness connector.
2.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR POWER SUPPLY
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR POWER SUPPLY CIRCUIT
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts
4.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR GROUND CIRCUIT
Turn ignition switch OFF.
Disconnect ECM harness connector.
Check the continuity between EVAP control system pressure sensor harness connector and ECM harness connector.
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
Check the EVAP control system pressure sensor. Refer to EC-311, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
