Checking the oil level 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.
- Check that the oil level in the engine is not too low. Ensure that the level is correct.
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.
