Where do you find camshaft position sensor for 91 cadillac deville?

The camshaft position sensor (CMP sensor) on a 1991 Cadillac DeVille is typically located on the passenger side of the engine, near the front of the cylinder head. However, the exact location can vary slightly depending on the engine (4.5L or 4.9L).

To be sure, you should:

1. Consult a repair manual: A Haynes or Chilton manual specific to your 1991 Cadillac DeVille will have diagrams showing the exact location of the CMP sensor. This is the best and most reliable method.

2. Use an online parts diagram: Many auto parts websites (like AutoZone, Advance Auto Parts, etc.) allow you to look up parts diagrams for your specific vehicle. Enter your VIN or year/make/model information, and find the diagram for the engine. The CMP sensor should be clearly labeled.

3. Visually inspect the engine: Once you've got a general idea from a manual or diagram, carefully look around the passenger side of the front of the engine. The sensor is usually fairly accessible and will have a wiring harness connected to it. Be aware that this area can be hot when the engine is running.

Caution: Before attempting any work on your engine, disconnect the negative battery terminal to prevent accidental short circuits.
