What are the symptoms of a faulty camshaft position sensor?

[LaAdeline]

The symptoms of a faulty camshaft position sensor include: 1. Difficulty in ignition and engine starting; 2. Difficulty in accelerating when the engine is hot; 3. Increased fuel consumption, lack of power, and difficulty in acceleration; 4. Engine trembling while driving. The function of the camshaft position sensor is to collect the position signal of the camshaft and input it into the electronic control unit to determine the ignition timing and fuel injection timing. The measurement method for the camshaft position sensor is: 1. Unplug the sensor's connector, turn the key to the second position, and use a voltmeter to confirm voltage output from the power line; 2. Connect one lead of the voltmeter to the confirmed power line and the other lead to the remaining two lines to identify the ground line (the one with voltage) and the signal line (the remaining one); 3. Turn off the key, connect the signal line, plug back the connector, and start the engine.
