On a car, the phase sensor is located in the cylinder head plug. The principle of the action phase sensor is based on the Hall effect. There is a special pin on the camshaft. When the pin passes against the end of the phase sensor, the phase sensor outputs a low level voltage pulse to the controller (approximately 0 V), which corresponds to the position of the piston of the 1st cylinder in the compression stroke.
To replace the phase sensor on a car, you will need a key «on 10».
1. Disconnect the wire from the terminal «minus» battery.
2. Press the plastic latch with wires away from the phase sensor.
3. Turn out two bolts of fastening of the gauge of a phase and remove it.
4. Install the phase sensor on the car in the reverse order of removal.
