The camshaft position sensor gathers and sends information about the vehicle’s camshaft speed, and sends it to the vehicle’s electronic control module. The computer receives this information and then uses the data to determine the timing of the ignition, as well as the timing of the fuel injection that the engine requires. Without this information, the engine would not be able to function properly. Over time, the camshaft position sensor can fail, or become worn down, due to accidents or normal wear and tear. There are a few warning signs to watch out for before your camshaft position sensor completely fails and shuts down the engine, indicating service may be required. 1. Vehicle does not drive like it used to If your vehicle has poor idling, frequent stalling, a drop in engine power, frequent stumbling, bad gas mileage, or abnormal acceleration, these are all signs your camshaft position sensor is failing. If you have any of these symptoms, this means the camshaft position sensor needs to be replaced by a professional mechanic as soon as possible. It needs to be completed before the engine cuts out and dies while you are driving, or does not start at all.

Hi Mark, I parked my car but when I returned it did not start. The battery is O.K and the engine turns over but it seems as though it is starved of petrol It has been suggested to me that the problem could be the camshaft sensor. None of the other symptoms were apparent before the failure to start. Thank you very much for your response.


The camshaft sensor will not orwvent you from starting the car, that is another issue
