The first tool you will need is a repair manual. I recommend a Haynes repair manual for your year and model Nissan. There may be special tools involved so read the instructions carefully. They can break at the threaded portion or at the electrical connector so be careful during the removal. ---

Have you located the sensor?? You change it like you would a spark plug. Be careful with the wiring connector… ---

No I have not located it yet. Should it be easy to find and is it under the car?
