Circuit/System Testing
- Check the fuel filler cap and seals for damage and proper installation
- If cap is loose, tighten cap until a ratcheting sound is heard.
- If damage or wear is found, replace the fuel filler cap.
- If no problems are found with the fuel filler cap.
- Raise the vehicle and disconnect the EVAP filter inlet hose at the quick connect fitting and plug the inlet to the filter with a J-41413-323
.
- Lower the vehicle and connect the GE 41413-A
to the purge line on the EVAP canister side of the EVAP purge solenoid valve using the J-41413-311
EVAP plug adapter.
- Use the GE 41413-A
to introduce nitrogen and fill the EVAP system until the floating indicator stabilizes. It may take several minutes for the float to stabilize.
- Use the flow meter on GE 41413-A
, calibrated to 0.51 mm (0.020 in), to determine that there is no leak in the evaporative emission system.
- If a leak is detected, use the GE 41413-A
to apply smoke to the EVAP system at the purge tube until the leak is located using the GE-41413-SPT
white light.
- Check the EVAP Canister Vent Solenoid Valve. refer to DTC P0447 or P0448 .
- Check EVAP canister. Refer to Component Testing.
- Check the EVAP Purge Solenoid Valve operation. Refer to DTC P0444 or P0445 .
- Check all EVAP hoses for damage or obstruction and repair or replace as necessary.
