Tools You'll Need:
* Socket set (metric)
* Ratchet and extensions
* Possibly a wrench for the sensor connector
* New camshaft position sensor (ensure you get the correct part for your engine)
* Shop rags or paper towels
* Possibly a small flathead screwdriver (depending on sensor connector type)
Steps:
1. Disconnect the Battery: This is crucial to prevent electrical shorts and potential damage to your vehicle's computer system. Disconnect the negative (-) terminal first.
2. Locate the Camshaft Position Sensor: The CMP sensor is usually located on the top of the engine, near the camshaft. It's a small sensor with a single electrical connector. Its exact location may vary slightly depending on the engine configuration. Consult a repair manual or online diagrams for your specific engine.
3. Disconnect the Electrical Connector: Carefully unplug the electrical connector from the sensor. Sometimes, a small flathead screwdriver is helpful to pry the connector open. Note how the connector is oriented for easy reassembly.
4. Remove the Sensor: The sensor is usually held in place by a single bolt or sometimes two. Use the appropriate socket to remove the bolt(s). The sensor itself may be slightly stubborn; gently wiggle and pull it out. Be careful not to damage the sensor threads or the engine block.
5. Clean the Area: Use a clean shop rag to remove any dirt, oil, or debris from the sensor mounting location. This ensures a clean seal for the new sensor.
6. Install the New Sensor: Carefully install the new camshaft position sensor into the mounting location, ensuring it's seated correctly. Tighten the bolt(s) to the manufacturer's specified torque (consult your repair manual). Do not overtighten.
7. Reconnect the Electrical Connector: Securely re-connect the electrical connector to the new sensor, ensuring it clicks into place.
8. Reconnect the Battery: Reconnect the battery's negative (-) terminal.
9. Test and Clear Codes (Optional but Recommended): Start the engine and check for any error codes. If your vehicle has a check engine light, use an OBD-II scanner to check for trouble codes. If any codes related to the camshaft position sensor are present, clear them using the scanner. Test drive the vehicle to ensure the issue is resolved.
Important Considerations:
* Repair Manual: Using a repair manual specific to your 1996 Chevrolet Cavalier 2.2L is highly recommended. It will provide detailed diagrams, torque specifications, and additional guidance.
* Safety: Always exercise caution when working on your vehicle. Use jack stands if you need to lift the car. Be mindful of moving parts and hot surfaces.
* Part Selection: Make sure you purchase the correct camshaft position sensor for your specific engine. The wrong part will not work.
If you're uncomfortable performing this repair yourself, it's always best to take your vehicle to a qualified mechanic. Improper repair could lead to further engine damage.
