Checking for oil leakage and replacing the oil level sensor
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.
