Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
- Inspect for a loose, missing, damaged, or incorrect fuel fill cap.
- Inspect for a damaged fuel filler neck seal surface.
- A blockage or restriction in the evaporative emission purge solenoid valve, purge pipe, evaporative emission canister, or vapor pipe, can cause this DTC to set.
- The evaporative emission system can be filled with smoke more quickly and completely by opening the system opposite the end where the smoke is injected. Close the system once smoke is observed.
- To help locate intermittent leaks using the J 41413-200: EEST, move all evaporative emission components while observing smoke with the J 41413-SPT: White Light.
- Individual components can be isolated and tested using adapters in the J 41413-300: Kit.
- A condition may exist where a leak in the evaporative emission system only exists under a vacuum condition. This type of leak may be detected by using the scan tool Purge/Seal function to create a vacuum in the evaporative emission system and then observe the fuel tank pressure parameter for vacuum decay.
