What are the causes of a faulty camshaft position sensor?

[LaSebastian]

The causes of a faulty camshaft position sensor are: 1. Failure of the camshaft position sensor component, wiring, or ECM; 2. Engine timing failure; 3. Failure of the camshaft variable timing adjustment section; 4. Faulty or abnormal gap in the camshaft position sensor target wheel; 5. Faulty crankshaft position sensor. The function of the camshaft position sensor is to collect the camshaft movement angle signal and input it into the electronic control unit to determine the ignition timing and fuel injection timing. Effects of a faulty camshaft position sensor: 1. Difficulty or inability to start the engine; 2. Increased fuel consumption; 3. Illuminated engine fault light; 4. Increased likelihood of engine knocking.
