The camshaft position sensor is a vital component of the engine management system. It is responsible for monitoring the position of the camshaft and relaying this information to the engine control unit (ECU). The ECU uses this information to control ignition timing and fuel injection timing.
The CMP sensor is located on the right side of the engine, at the rear of the valve cover. It is important to note that the sensor is mounted beneath the timing belt cover.
When troubleshooting or replacing the CMP sensor, it is important to consult your vehicle’s service manual for specific instructions.
How to tell if the CMP sensor is bad or needs to be replaced?
There are a few different reasons why a CMP sensor may go bad, including age, contamination, and physical damage. Symptoms of a bad CMP sensor can include engine misfires, stalling, and a reduction in power. The check engine light may also come on if the sensor is faulty.
In most cases, these issues can be fixed by replacing the CMP sensor. The cost of doing so will vary depending on the make and model of your vehicle, but it is typically an inexpensive repair.
Always consult your service manual or local auto mechanic for more specific instructions before attempting to replace the CMP sensor yourself.
How much will it cost to replace the camshaft position sensor?
The cost of replacing the CMP sensor will vary depending on the make and model of your vehicle. It is typically a relatively inexpensive repair, costing around $200 or less.
However, some luxury vehicles may cost more to repair. Consult your service manual or a local auto mechanic for an estimate.
How to safely replace camshaft position sensor – Step-by-Step
Replacing the CMP sensor is a relatively simple repair that can be completed by most do-it-yourselfers.
Assuming you have the correct replacement CMP sensor for your vehicle, follow these steps to safely replace it:
- Park your car in a safe and level location. Be sure to set the parking brake to prevent the car from rolling.
- Disconnect the negative battery terminal to prevent electrical shocks.
- Locate the CMP sensor. It is typically located on the right side of the engine, at the rear of the valve cover.
- Unplug the electrical connector from the sensor.
- Using a ratchet and socket, remove the bolts that hold the sensor in place.
- Remove the old sensor and install the new one.
- Reconnect the electrical connector to the new sensor.
- Reinstall the bolts that hold the sensor in place.
- Reconnect the negative battery terminal.
- Start the car and test drive it to ensure proper operation.
ProTip: You may need to also clear the check engine light from your car’s computer system after replacing the CMP sensor. This can typically be done by disconnecting the battery for 30 seconds or more.
