Hello, I was trying to find the location of the sensor due to the fact I had the engine light come on. It is a p0128 code, which Autozone said is either thermostat or sensor so I figured I would change both. Thanks.

Do you have a 3.0 or 3.5L engine? More then likely it is a bad thermostat all the code P0128 I have seen on all different make cars has been a bad thermostat.

Thanks, I will check the engine, not sure what, but I figured the sensor was not expensive so I would just change it when I change thermostat. I still need to find out where the sensor is located. Appreciate the response.

On the emissions label under the hood it should tell you what size the engine is.
