What does this fault code mean?

The ECM monitors the oil pressure with a combined oil pressure and oil temperature sensor. The oil pressure is compared with the ambient and boost pressures already when the ignition is switched on. The code is set when the engine is running and the difference is too large. The signal stays constantly high, and the fault lies in the sensor.

Possible causes

Oil pressure and oil temperature sensor is damaged

What you can do

1Check the connector to the oil pressure and oil temperature sensor for oxidation and loose contacts
2If you have a diagnostic tool, read the oil pressure in live data with the engine running and see whether the value stays at a constant high level
3Check the sensor wire for a short to supply voltage
4If the connector and wire are in order but the value stays high, 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
