To find it, you'll need to:
1. Consult a repair manual specific to your 1992 Cadillac DeVille's engine: This is the most reliable method. The manual will have diagrams and precise locations. You can find these manuals online (e.g., Haynes, Chilton) or at auto parts stores.
2. Look near the front of the engine: The CMP sensor is typically located on the engine block or cylinder head, near the camshaft sprocket or the distributor (if equipped). It's often a small sensor with a single or two-wire connector.
3. Use online resources cautiously: While some online forums or diagrams might help, they aren't a replacement for a proper repair manual. Incorrect identification can lead to further damage.
Without knowing the exact engine code, it's impossible to give a precise location. Look for the sensor near the camshaft's gear, often at the top or side of the engine block/head in that area.
Remember to disconnect the negative battery terminal before attempting any work on the vehicle's electrical system.
