- The camshaft position sensor for a BMW diesel engine can vary depending on the specific engine model.
Here are the general steps to locate the CMP sensor on a BMW diesel engine:
1. Open the Hood: Open the hood of your BMW and secure it in the open position.
2. Locate the Engine: Identify the diesel engine in your BMW.
3. Find the Cylinder Head Cover: On the top of the engine, you'll find the cylinder head cover. It's usually a black or silver cover held down by bolts.
4. Check for Sensor: Inspect the cylinder head cover and look for a small, cylindrical sensor. This sensor might have "CMP" or "CAM" written on it, indicating it's the camshaft position sensor.
5. Sensor Location: The CMP sensor is typically located near the camshaft. It's often installed directly on the camshaft housing or camshaft cover.
6. Wiring Harness: Trace the wiring harness from the CMP sensor to identify its connection to the engine control unit (ECU) or engine wiring harness.
Additional Notes:
- In some BMW diesel models, the CMP sensor might be located near the camshaft drive pulley or the timing belt cover.
- There could be multiple CMP sensors on some BMW diesel engines.
- Always consult your vehicle's specific repair manual or documentation to confirm the exact location and any specific instructions for your particular model.
