Some original equipment manufacturers (OEMs) can choose to install an additional temperature sensor.

The OEM temperature sensor monitors an OEM-defined temperature and passes that information on to the electronic control module (ECM) through the OEM harness. The ECM uses this information to determine the state of an OEM switched output device.

Refer to the OEM troubleshooting and repair manual for the location of the OEM temperature sensor.

Inspect the OEM temperature sensor for damaged or broken connector pins.
