Hi,

There are actually two on this vehicle. One is located at the thermostat housing and the other is in the radiator.

The one in the radiator is used to control the cooling fans. The one in the thermostat housing is used by the powertrain control module.

I attached a picture of both below. Let me know if this helps.

Take care,

joe
