What is a Camshaft Position Sensor?

The camshaft position sensor relays important information to the engine control module (ECM). The ECM needs to know both the position and the speed of the camshaft, in order to help the engine operate properly and efficiently.

Attached to the camshaft is a notched or toothed wheel, which works with the position sensor, and rotates along with the camshaft. The position sensor gets the position and speed information from the wheel, and sends it to the ECM. That allows the ECM to know when to fire the fuel injectors. The ECM may also  use information from the sensor to determine ignition timing and variable valve timing, and to notice when the engine is having a misfiring issue.

Signs of a malfunctioning Camshaft Position Sensor

Check engine light is on

The check engine light can come on for a variety of reasons. One of them is a camshaft position sensor that is broken.

Performance problems

If the camshaft position sensor isn’t working properly, the ECM won’t have the information it needs. When that happens, the engine won’t operate correctly, and you’ll likely experience a lack of power, some rough riding, and some misfiring.

Stalling

A malfunctioning camshaft position sensor can also cause your car to stall. Because the ECM isn’t getting the information it needs, the engine may not be able to idle.

Car won’t start

It’s also possible that an inoperable camshaft position sensor will keep the vehicle from even being able to start.

How urgent is a Camshaft Position Sensor replacement?

A failing camshaft position sensor is unlikely to cause any further damage to your car. However, your car will be unreliable, as it will have stalling issues and may not be able to start. The sensor should be replaced as soon as possible.
