To find it, you'll need to:
1. Identify your engine: Check your vehicle's documentation or the engine block itself for the displacement (e.g., 4.8L, 5.3L, 6.0L).
2. Consult a repair manual: A repair manual specific to your Suburban's year and engine will show you a diagram with the sensor's precise location. These manuals often have photos and detailed instructions. You can find these online or at auto parts stores.
3. Use online resources: Websites like AutoZone, Advance Auto Parts, or others often have diagrams and repair guides. Search for your specific year, make, model, and engine.
General areas to look: The CMP sensor is usually located on the engine's front or passenger side, near the camshaft. It's often mounted on the cylinder head or the valve cover. It's a fairly small sensor, often with a single wire connector.
Caution: Working on your vehicle's engine can be dangerous. If you're not comfortable doing this yourself, take it to a qualified mechanic. Incorrectly handling engine components can lead to damage.
