Signs of a malfunctioning Camshaft Position Sensor

Check engine light is on

Your vehicle's check engine sensor light can come on for a variety of reasons. One of them is a position sensor that is broken. A check engine sensor light could be symptom of a camshaft sensor that needs a replacement.

Performance problems

If the camshaft position sensor isn’t working properly, the ECM won’t have the information it needs, leading to potential incorrect ignition timing and poor engine performance. When the position sensor needs a replacement, the engine won’t operate correctly, and you’ll likely experience a lack of power, some rough riding, and some misfiring. If your vehicle is experiencing these symptoms, you might want to get your camshaft sensor checked-out.


A malfunctioning camshaft position sensor can also cause your vehicle to stall. When the camshaft sensor needs a replacement, the ECM isn’t getting the information it needs and the engine may not be able to idle. If your vehicle is frequently stalling, considering checking your position sensor.

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, if you continue driving with a faulty camshaft sensor, your vehicle will be unreliable. A bad sensor leads to stalling issues and the camshaft sensor may even prevent your vehicle from starting. The sensor should be replaced as soon as possible.
