STEP 1. Using scan tool (M.U.T.-IIISE), check actuator test item 4: Evaporative Emission Purge Solenoid ON.
STEP 2. Check the evaporative emission purge solenoid.
STEP 3. Measure the power supply voltage at evaporative emission purge solenoid harness side connector.
(1) Disconnect the evaporative emission purge solenoid connector and measure at the harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal power supply line and ground.- Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is battery positive voltage (approximately 12 volts) present?
Go to Step 4. Repair or replace the connector(s), or check and repair the harness of short to ground and open circuit in power supply line between MFI relay connector and evaporative emission purge solenoid connector. Then go to Step 8.
STEP 4. Measure the power supply voltage at ECM connector.
(1) Disconnect connector, and measure at harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal PURG and ground.- Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is battery positive voltage (approximately 12 volts) present?
Go to Step 5. Repair or replace the connector(s), or check and repair the harness of short to ground and open circuit in PURG line between evaporative emission purge solenoid connector and ECM connector. Then go to Step 8.
STEP 5. Check of harness damage in PURG line between evaporative emission purge solenoid connector and ECM connector.
STEP 6. Check of harness damage in power supply line between MFI relay connector and evaporative emission purge solenoid connector.
STEP 7. Using scan tool (M.U.T.-IIISE), check actuator test item 4: Evaporative Emission Purge Solenoid ON.
STEP 8. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to Diagnostic Function - OBD-II Drive Cycle - Pattern 1 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0458 set?
Retry the troubleshooting. The inspection is complete.
