YES
>> GO TO 4.
NO
>> Repair open circuit, short to ground or short to power in harness or connectors.
4.
CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR CONNECTOR
1.
Disconnect EVAP control system pressure sensor harness connector.
2.
Check that water is not inside connectors.
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Replace EVAP control system pressure sensor. Refer to
5.
CHECK EVAP CONTROL SYSTEM PRESSURE SENSOR
EC-312, "Component Inspection"
Is the inspection result normal?
YES-1 >> With CONSULT: GO TO 6.
YES-2 >> Without CONSULT: GO TO 7.
NO
>> Replace EVAP control system pressure sensor. Refer to
6.
CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
With CONSULT
1.
Turn ignition switch OFF.
2.
Reconnect harness connectors disconnected.
3.
Start engine.
4.
Perform “PURG VOL C/V” in “ACTIVE TEST” mode with CONSULT. Check that engine speed varies
according to the valve opening.
Does engine speed vary according to the valve opening?
