What is a Camshaft Position Sensor?
The camshaft position sensor is a vital component in the engine management system. It monitors the position of the camshaft, which controls the opening and closing of the intake and exhaust valves. This information is used by the engine computer to calculate the fuel injection and ignition timing.
Symptoms of a Bad Camshaft Position Sensor
A faulty CPS can cause a variety of symptoms, including:
- Engine stalling
- Rough idling
- Loss of power
- Check engine light illumination
- Difficulty starting

Step-by-Step Replacement Guide
1. Safety Precautions
Wear safety glasses and gloves throughout the procedure. Allow the engine to cool down before working on it.
2. Locate the Camshaft Position Sensor
The CPS is located on the back of the engine, near the top of the cylinder head. It is typically held in place by a single bolt.
3. Disconnect the Electrical Connector
Use the 10mm socket wrench to disconnect the electrical connector from the CPS.
4. Remove the Mounting Bolt
Use the 12mm socket wrench to remove the mounting bolt that secures the CPS.

Once the mounting bolt is removed, gently pull the old CPS straight out of its housing.
6. Insert the New CPS
Align the new CPS with the housing and push it in firmly until it is fully seated.
7. Tighten the Mounting Bolt
Use the 12mm socket wrench to tighten the mounting bolt to the specified torque.
8. Reconnect the Electrical Connector
Plug the electrical connector back into the new CPS.
9. Start the Engine
Start the engine and check for any leaks or unusual noises. If everything looks and sounds good, your CPS replacement is complete.
Tips for Success
- Use a flashlight to illuminate the work area if necessary.
- Be careful not to overtighten the mounting bolt.
