The camshaft position sensor of the automobile is damaged, the idle speed of the automobile is unstable, the vibration is serious, the oil consumption of the automobile is high, the exhaust emission exceeds the standard, and the exhaust pipe emits unpleasant black smoke.
The camshaft position sensor (phase) senses the position of the camshaft protrusion to identify the working cylinder. The camshaft position sensor senses the position of the piston. When the crankshaft position sensor (position) system fails, the camshaft position sensor (phase) will use the timing of the cylinder identification signal to provide different control for each engine part.

Precautions for camshaft position sensor:
1. The ECM detects that the intake camshaft position actuator solenoid valve and the exhaust camshaft position actuator solenoid valve are continuously opened for more than 1 second or accumulated for 5 seconds, and the camshaft position sensor fails.
2. When the actual camshaft position does not match the commanded position of the electronic control unit, the camshaft position sensor will fail. One is an electronic fault, and the other is a mechanical fault caused by the accumulation of foreign bodies at the rear end of the camshaft and the damage of the signal board.
3. The camshaft position sensor (phase) senses the protruding position of the camshaft to identify the working cylinder. The camshaft position sensor senses the position of the piston. When the crankshaft position sensor (position) system fails, the camshaft position sensor (phase) will use the timing of the cylinder identification signal to provide different control for each engine part.
