Services Performed
- VEHICLE SERVICE: – CHANGE ENGINE OIL AND FILTER – TIRE INFLATION CHECK – BRAKE COMPONENT INSPECTION – ALL FLUID LEVEL CHECK – RESET MAINTENANCE COUNTER
- Connected a scan tool and found code P0455 – Evaporative Emission System Leak Detected (Large Leak). Performed a visual inspection of the evaporative emission (EVAP) system to check for any signs of damage, but found no obvious faults. Connected a smoke machine to the EVAP system test port and induced smoke into the EVAP system to check for leaks. Used the scan tool to command the EVAP purge solenoid valve and the EVAP canister vent solenoid closed for the smoke test and found no signs of smoke, which indicated no external leaks were present. Continued to inspect the EVAP system by removing the vacuum source hose from the EVAP purge solenoid valve and observed smoke emitted from the EVAP purge solenoid valve, which indicated it leaked. Attached a vacuum pump to the EVAP purge solenoid valve and tested the valve by applying vacuum. The EVAP purge solenoid valve leaked and did not retain the applied vacuum. The results of these tests verified the EVAP purge solenoid valve was faulty. REMOVE ALL NECESSARY COMPONENTS. REMOVE AND REPLACE PURGE VALVE. ASSEMBLE TOGETHER AND MAKE ALL NECESSARY ADJUSTMENTS. TEST ALL AFFECTED AREAS.
