What does this fault code mean?
The ECM monitors the oil pressure with the combined oil pressure and oil temperature sensor and constantly checks that the value stays within a fixed range. The code is set when the oil pressure falls outside the range while the engine is running. The fault may be poor contact, a signal wire shorted to ground, or a damaged sensor.
Possible causes
- Contact resistance or oxidation in connections
- Signal wire shorted to ground
- Oil pressure and oil temperature sensor is damaged
What you can do
- 1Check the sensor connector for contact resistance and oxidation
- 2Use a multimeter to check that the sensor signal wire is not shorted to ground
- 3If you have a diagnostic tool, read the oil pressure in live data with the engine running and see whether it is outside the range all the time or only sometimes
- 4If the connector and wire are in order, the sensor is probably damaged and needs replacing
- 5Clear the code and start the engine to see whether it returns
- 6If the fault returns, have a workshop with diagnostic equipment check the sensor and its signal
Symptoms you may notice1
- No noticeable symptoms for the driver
