STEP 1. Using scan tool MB991958, check actuator test item 10: Evaporative Emission Purge Solenoid.
caution | To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958. |
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set scan tool MB991958 to the actuator test mode for item 10, Evaporative Emission Purge Solenoid.- An operation sound should be heard and vibration should be felt when the evaporative emission purge solenoid is operated.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Is the solenoid operating properly?
It can be assumed that this malfunction is intermittent. Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions . Go to Step 2.
STEP 2. Check harness connector B-28 at evaporative emission purge solenoid for damage.
STEP 3. Check the evaporative emission purge solenoid.
(1) Disconnect the evaporative emission purge solenoid connector B-28.
(2) Measure the resistance between evaporative emission purge solenoid side connector terminal No. 1 and No. 2.Standard value: 22 - 26 Ω [at 20°C (68°F)]
Is the measured resistance between 22 and 26 Ω [at 20°C (68°F)]?
Go to Step 4. Replace the evaporative emission purge solenoid. Then go to Step 7.
STEP 4. Check harness connector B-26 at MFI for damage.
STEP 5. Check of short to power supply between MFI connector B-26 (terminal No. 37) and evaporative emission purge solenoid connector B-28 (terminal No. 1).
STEP 6. Using scan tool MB991958, check actuator test item 10: Evaporative Emission Purge Solenoid.
STEP 7. 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 23 . (2) Check the diagnostic trouble code (DTC).
Is DTC P0459 set?
Retry the troubleshooting. The inspection is complete.
