High Oil Temperature, Reduce Engine Rpm

The instrument panel cluster (IPC) illuminates the HIGH OIL TEMPERATURE message and then the REDUCE ENGINE RPM messages in the driver information center (DIC) in 3 second intervals if the IPC detects that the engine oil temperature exceeds 160°C (320°F). The IPC monitors the engine oil temperature signal circuit to determine the engine oil temperature. A low resistance indicates high engine oil temperature.
