To be certain, you'll need to:
1. Consult your vehicle's repair manual: This is the most reliable source. The manual will have a diagram showing the exact location.
2. Look at online diagrams: Websites like AutoZone, Advance Auto Parts, or Haynes manuals often have online diagrams for your specific year and engine. Search for your vehicle's specifications.
3. Visually inspect the engine: Once you've located the oil filter, look closely in that general area for a small switch with one or two wires connected. It's often a smaller switch compared to other components in the vicinity.
Remember to be careful when working near hot engine components. Let the engine cool completely before attempting to locate the switch.
