Can camshaft sensor cause knocking?

4. Bad Fuel Economy. Inaccurate camshaft position sensor data can keep fuel injectors open too long, forcing excess fuel into the combustion chamber. This also can cause engine knocking and serious damage if too much liquid gasoline (which does not compress) builds up in the combustion chamber.

Can a crankshaft position sensor cause a knock?

Unfortunately, a crank sensor will not cause the engine to knock. This sensor helps the computer control ignition system timing, and has nothing to do with crankshaft operation, other that telling what position it is in. If the sensor is bad, or damaged, the engine will not run at all.

What does the camshaft position sensor do on a BMW?

Click here to order! The camshaft position sensor is used to synchronize fuel injection and as a feedback device for VANOS (variable camshaft timing) control. When a camshaft sensor fails, the check engine light will illuminate and a fault code will be stored.

When to check a camshaft position fault code?

When you are dealing with camshaft position fault codes, be sure to test the sensor and confirm it is faulty. Other items could also set a camshaft position fault code, for example a dirty or defective VANOS solenoid. If you have a fault code for either camshaft position sensor, check the VANOS solenoid first.
