Faulty Signal

Faulty signal

Checking for oil leakage and replacing the component

Note! If diagnostic trouble codes (DTCs) ECM-540X and ECM-550X are stored at the same time, codes ECM-540X must be remedied first.

- Checking the engine for oil leakage
- Also check the oil level sensor connector. Check for loose connections, contact resistance or oxidation.

Hint: This diagnostic trouble code (DTC) may be stored if the engine oil is significantly mixed with fuel or coolant for example.

Try a new oil level sensor if no fault is found and the fault is permanent.
Remedy as necessary.

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








- Ignition off
- Reinstall the connectors, components etc.
- Start the engine. Allow the engine to idle for 1 minute. Increase the engine speed (RPM) to approximately 5100 rpm for at least 1 second. The car must then be driven at a speed of more than 50 km/h.

Note! The above instructions must be followed and carried out in the specified order.

- Read off the status of the diagnostic trouble code (DTC).
The fault has been remedied if status of the diagnostic trouble code (DTC) is intermittent.
