Camshaft position sensor replacement
How much does a camshaft position sensor replacement cost?
Modern cars all have an electronic ignition system to control the engine’s operation, and a key component to make it work is the camshaft position sensor.
Using your car normally, the camshaft position sensor can often last an engines whole lifetime without requiring replacement.
However, it’s an electrical part, and unexpected failure is a possibility at any time, whether the car is new or getting on in years.
The average price to have the camshaft position sensor replaced begins around $220 and ranges up to $450 in most cases, depending on the make and model you drive.
Some cars have two camshafts, thus there are two camshaft position sensors.
What is a camshaft position sensor?
A camshaft position sensor is a hall effect sensor, meaning it uses magnetic force to create an electronic signal.
The camshaft position sensor is installed by the front of the camshaft and monitors the position of a wheel attached to the shaft itself.
You’ll find most engines will have one camshaft position sensor for each camshaft, so a dual overhead cam engine will have two camshaft position sensors.
The sensor contains a magnet and solenoid windings inside and the body of the sensor is molded plastic.
A wiring harness connector transmits the camshaft position sensor signal to the Engine Control Module.
If the sensor reads erratically, is unresponsive, or is physically broken, it will need to be replaced.
