To be certain, you'll want to:
* Consult a repair manual specific to your engine's year: This is the most reliable way to pinpoint its exact location. A Haynes or Chilton manual will be very helpful.
* Look at diagrams: Online parts diagrams for your specific year and model Dodge vehicle can show you the location. Enter your year, make, model, and engine into a parts website like AutoZone, Advance Auto Parts, or RockAuto.
* Visually inspect the engine: Look for a small sensor with one or two wires connected near the oil filter and oil pump area on the driver's side of the engine block.
Remember to disconnect the battery's negative terminal before working on any electrical components.
