What does a CMP sensor do?
The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection that the engine requires.
What is a CMP sensor signal?
A CMP sensor signals one or more fixed camshaft reference positions to the Engine Control Module (ECM), for example, the arrival of a cylinder’s intake stroke. The ECM uses the camshaft sensor signal for accurate timing control of ignition (if a gasoline engine), injection, and variable valve phasing, etc.
How much does it cost to replace a CMP sensor?
To replace a camshaft position sensor, you can expect to pay anywhere from $95 to $200. Parts alone will run about $25 to $100. Labor costs will be in the range of $70 to $100 for professional replacement. Expect to pay more if you have a luxury vehicle or are having your local car dealership perform the replacement.

What can cause a P0345 code?
What Is The Cause Of Code P0345?
- A defective camshaft position sensor.
- Damaged or dirty reluctor ring on the camshaft.
- Defective, corroded, shorted camshaft position sensor circuit wiring.
- Defective, corroded, shorted camshaft position sensor circuit connector.
- A faulty crankshaft position sensor.
How do you test a CMP sensor?
Touch one of your meter probes to either one of the sensor wires and the other to the other wire. Check your meter display and compare your reading to your manual specifications. In most cases, you’ll see a fluctuating signal between 0.3 volts and 1 volt. If there’s no signal, you have a bad sensor.
What type of sensor is a CMP?
Camshaft position sensor is also called cylinder identification sensor or phase detector. In consecutive fuel injection systems, ECU must determine which cylinder to fire next. This information is provided from the cylinder identification sensor.
Can I drive with a bad camshaft sensor?
Yes, it is safe to drive with a bad camshaft sensor. However, the performance of your engine will not be as good and fuel consumption may increase. In some cases, the camshaft may need replacement if there are any other symptoms of failure on this component.
What are the symptoms of a bad crankshaft sensor?
