(Contact tie-in) make the digital multimeter in A/C voltage gear, the two needles should be connected to
stitch 2 0and stitch 30, then start the engine, there will be voltage output. (Advice: check by oscillograph)

Phase Sensor
The phase sensor is to check the sensor of engine timing phase which is usually got by checking the turning
angle of the position of the camshaft.

Working Principle
The sensor takes advantage of the Hall Principle, and the Hall Voltage is influenced by the changed magnetic
induction intensity.
Hall Sensor Principle
When the electricity current Is pass through a semiconductor flake, on the way of voltaic dextral will produce
Hall voltage U
H, its
value with magnetic field induction B(vertical to current Is) and current Is is directly
