To find any sensors associated with your power steering system, you'll need to:
* Consult a repair manual: A Haynes or Chilton manual specific to your 2001 Dodge Durango will show diagrams and pinpoint the location of any pressure sensors or switches related to the power steering pump and system.
* Check online resources: Websites like AutoZone, Advance Auto Parts, or similar parts retailers often have diagrams and information. Search for your vehicle year, make, and model and look at their power steering system diagrams.
* Inspect the power steering pump itself: The most likely place for a sensor is directly on or very near the power steering pump.
Remember to be cautious when inspecting components under the hood. The engine and related components are hot after operation.
