Signal Too High

Signal too high

Checking the status




- Ignition on
- Read off the oil level sensor signal.
The values indicate the pulse ratio of the oil level signal, the oil temperature signal and the oil quality signal based on the combined pulse width modulated signal from the oil level sensor. All these signals are used by the engine control module (ECM) to calculate the oil level.
Check that all three values for oil level, oil temperature and oil grade are between 17-83%. The fault is intermittent at the moment if all the values are OK.

Checking the wiring and component

Hint: If any of the signal values from the oil level sensor are incorrect but at least one is correct, the oil level sensor is damaged.

Check the signal cable between engine control module (ECM) terminal #A68 (#B8) and oil level sensor terminal #1. Check for a short-circuit to supply voltage.

Hint: With the ignition on, the voltage between terminals #2 and #3 must be 5 V, with the reading taken at the oil level sensor connector.

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
- Reconnect the connectors, reinstall components etc.
- Ignition on.
Read off the oil level sensor signal.
Check that all three values for oil level, oil temperature and oil grade are between 17-83%. The fault has been remedied if all the values are OK.





Are these values OK?

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.
