Verification

HINT: After carrying out the repair, check that the fault has been remedied.

Scheme 130

If the engine is running unevenly or is jerky, this may indicate misfiring.

1. Reinstall the components, reconnect the connectors etc.
2. Start the engine. Check immediately that there is no misfiring
3. Let the engine idle. Check that there is no misfiring
4. Rev the engine. Check that there is no misfiring as engine speed increases, at constant engine speeds and when returning to idle speed. HINT: It may be difficult to detect misfiring in the workshop. Further checks can be made when carrying out the final checks after the diagnostic trouble codes (DTCs) have been erased.

Is the engine misfiring?

1. YES Refer to «Information»(ref-441346-S03331241362011121500000)
2. NO VERIFIED: Troubleshooting has been completed.

The fault should have been detected and remedied. As this is not the case fault-tracing has failed.

By activating the leak diagnostic the status (permanent/intermittent) of the fault can be determined. The fault is intermittent if this diagnostic trouble code (DTC) is detected without any fault being found when the leak diagnostic is run.

If the size of the leak is unknown (qualifier unknown) when reading off diagnostic trouble codes (DTCs) the size of the leak can be determined in the tank system quick test if the fault is permanent.

Check that the hoses, connectors and components etc. have been correctly reinstalled. Check that they are not damaged.

Intermittent fault

The control module has previously detected a leak in the tank system but the fault is no longer active. The fault may be due to leakage in the fuel tank, fuel filler pipe, fuel tank filler cap, EVAP canister, Canister purge (CP) valve, leak diagnostic pump or in the hoses between these components.

HINT: This DTC can be stored if the car is driven without the fuel tank filler cap or if the fuel tank filler cap is incorrectly tightened.
