How To Reset Camshaft Position Sensor?

Resetting the camshaft position sensor can resolve many engine issues related to improper camshaft timing. Follow the steps to properly disconnect and reconnect the sensor and allow the vehicle’s computer to re-learn the sensor position.

In some cases, resetting the sensor can help resolve these issues. Here is how to reset the camshaft position sensor:

Step 1: Turn off the engine

Before resetting the camshaft position sensor, turn off the engine and wait for it to cool down. This will prevent any accidental damage to the engine or the sensor.

Step 2: Disconnect the battery

Next, disconnect the battery to prevent any electrical surges or damage to the electrical components. Locate the battery's negative terminal and use a wrench or pliers to loosen the bolt. Once the bolt is loose, you can remove the negative cable from the battery.

Step 3: Locate the camshaft position sensor

The camshaft position sensor is usually located near the top of the engine block, near the camshaft. Refer to your car’s owner’s manual or a repair manual for the exact location of the sensor.

Step 4: Remove the sensor

To reset the camshaft position sensor, remove it from the engine. Use a socket wrench or pliers to remove any bolts or screws that are holding the sensor in place. Once you have removed the sensor, inspect it for any damage or signs of wear and tear. If the sensor is damaged, you may need to replace it instead of resetting it.

Step 5: Clean the sensor

Clean it thoroughly with a cleaning solution and a soft cloth. Make sure that there is no debris or dirt on the sensor that could interfere with its operation. 

Step 6: Reconnect the sensor

Once you have cleaned the sensor, you can reinstall it in the engine. Use a socket wrench or pliers to tighten any screws or bolts holding the sensor in place.

Step 7: Reconnect the battery

Finally, you need to reconnect the battery. Reattach the negative cable to the negative terminal and use a wrench or pliers to tighten the bolt. Once the cable is securely attached to the battery, you can start the engine and test the camshaft position sensor.

Note: Sometimes, you may need to use an OBD-II scanner to reset the CPS. If you're unsure how to do this, consult your car's manual or take your car to a mechanic.

Resetting the camshaft position sensor can help resolve engine performance issues caused by a malfunctioning sensor. However, it is important to note that resetting the sensor may not always be the solution. If you continue to experience engine performance issues after resetting the sensor, you should consult a professional mechanic to diagnose and repair the problem.

What to Do If the CPS Reset Doesn't Work

If the reset does not work, it is likely that the CPS is bad and needs to be replaced. You can usually find a replacement CPS at your local auto parts store. When replacing the CPS, be sure to get a sensor compatible with your car’s make and model. You can find this information in the car's manual.

Replacing the CPS is a relatively simple job that can be done in about an hour. Check the check engine light. If it is still on, you may need to take your car to a mechanic to have the CPS reprogrammed.
