To be certain, you'll need to:
1. Consult your vehicle's repair manual: This will provide diagrams and precise instructions. A Haynes or Chilton manual for your specific year and engine is highly recommended.
2. Use a reliable online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to enter your vehicle's information and view diagrams showing the location of various components.
Important Note: Working on engine components can be dangerous. If you're not comfortable with auto repair, it's best to have a qualified mechanic locate and diagnose the sensor.
