How does a camshaft position sensor work in an engine?
Your engine’s camshaft position sensor is designed to count the rotations of the camshaft inside the engine as it is running. Using a metal timer somewhere on the camshaft this sensor uses a magnetic field which is built up and then broken down which counts as one revolution.
How to know when to replace your camshaft position?
The same procedure applies for the crankshaft sensor. Diagnose the problem through the process of elimination. Taking into consideration that the cam sensor has a direct effect on the operation of the fuel injectors and the crank sensor on the ignition, check for spark at the plugs. Pull one of the spark plug wires off one of the plugs.
How much does it cost to replace a camshaft sensor?
This action causes the engine to loose a small amount of power and fuel economy. Camshaft sensor service costs will vary per manufacturer and depend on the location of the sensor. If you are having the job done at a repair shop or at the dealer it will cost between $180.00 and $250.00 (US).
What happens when a camshaft sensor goes bad?
Symptoms of a Bad Camshaft Sensor. When a cam sensor goes bad it will cause the check engine light to come on and produce a trouble code. It can also cause the engine to run rough while the car is at cruising speed or at idle.
How much to replace a camshaft sensor?
Additional costs will be for the other engine parts that will support the camshaft and engine. A camshaft position sensor, which may be needed or replaced, can can cost $100 to $350 for the part.
Where is the cam position sensor located?
The camshaft position sensor is either located near the top of the engine, passenger-s side, or on the right side of the engine near the ignition coils. The camshaft position sensor is located on the engine near the camshaft pulley.
What does a cam position sensor do?
The CAM sensor or camshaft position sensor’s role is to signal the ECM the camshaft position. The crank and cam sensor operates in sync with eachother. The CAM sensor is frequently used in determining which injector to fire in a sequential system and for the COP or coil on-plug ignition systems coil firing event.
What is cam position sensor?
A cam position sensor is a component used to monitor the position of the camshaft. This information is used by the ECM (ECU) to control ignition system timing and other engine parameters.
