To be certain, you should:
* Consult your vehicle's repair manual: This is the most reliable source. It will have diagrams and precise location information.
* Use a reliable online parts diagram: Many websites, like AutoZone, Advance Auto Parts, or RockAuto, allow you to enter your vehicle's information and see diagrams showing the sensor's location.
Important Note: Accessing this sensor often requires some mechanical skill and potentially some specialized tools. If you're not comfortable working on your car, it's best to take it to a qualified mechanic.
