Hi,

Chances are the temperature sensor is bad and therefore, the system, not knowing the temp, assumes it is overheating.

That is the first thing I suspect is the problem. However, make sure it isn't disconnected first and inspect the wiring to it as well as the connector.

If you determine it needs to be replaced, here is a link to help get you started:

If you look at the attachments below, they are specific to your vehicle and the picture shows the location of the sensor.

Let me know if this helps or if you have other questions.

Take care,

Joe
