This is from the manual.
The camshaft position sensor (PHASE) is located on the engine
front cover facing the camshaft sprocket. It detects the cylinder No.
signal.
The sensor consists of a permanent magnet, core and coil.
When engine is running, the gap between the sensor and the
camshaft sprocket will periodically change. Permeability near the
sensor also changes.
Due to the permeability change, the magnetic flux near the core is
changed. Therefore, the voltage signal generated in the coil is
changed.
The ECM receives the voltage signal and detects the cylinder No.
signal.
Also, if you measure the resistance, it should be 1440-1760 for a Hatachi make and 2090-2550 for Mitsubishi make. That will prove if the sensor is actually bad.
