STEP 1. Using scan tool (M.U.T.-III), check actuator test item 15: Evaporative Emission Ventilation Solenoid.
STEP 2. Check the evaporative emission ventilation solenoid.
(1) Disconnect connector, and measure at solenoid side.
(2) Measure the resistance between evaporative emission ventilation solenoid side connector terminals.Standard value: 17 - 21 Ω [at 20°C (68°F)]
Is the measured resistance between 17 and 21 Ω [at 20°C (68°F)]?
Go to Step 3. Replace the evaporative emission ventilation solenoid. Then go to Step 5.
STEP 3. Check of short circuit to power supply in P/VT line between evaporative emission ventilation solenoid connector and ECM connector.
STEP 4. Using scan tool (M.U.T.-III), check actuator test item 15: Evaporative Emission Ventilation Solenoid.
STEP 5. 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 22 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0499 stored?
Retry the troubleshooting. The inspection is complete.
