To be certain, you should:
* Consult your owner's manual: This is the best source for your specific vehicle.
* Use a repair manual specific to your year and engine: Chilton's or Haynes manuals often have diagrams showing sensor locations.
* Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your year, make, model, and engine to see parts diagrams.
Looking at a parts diagram will give you the most precise location. Remember to be careful when working near the engine, and always disconnect the negative battery terminal before starting any work.
