However, precise location can vary slightly depending on the engine type (3.9L or 4.2L V6). A repair manual specific to your vehicle's engine will give the most accurate location and visual aid. You can find these manuals online (often as PDFs) or at auto parts stores.
A visual inspection, with the engine cover off (if applicable), will also help pinpoint the sensor's location. It's usually a relatively small sensor with a single or two-wire connector.
