To be certain, you'll need to:
* Consult a repair manual specific to your 2002 Ford Escape V6: This is the most reliable method. The manual will have diagrams showing the exact location of each sensor.
* Use a reliable online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to select your vehicle's year, make, and model and view diagrams showing the sensor locations.
Without a visual aid, pinpointing the exact location is difficult, as slight variations can exist depending on specific engine configurations within the same model year. Always double-check using the methods above before attempting any work on your vehicle.
