any other codes?
The camshaft position sensor (PHASE) senses the retraction of intake valve camshaft to identify a particular cylinder. The camshaft position sensor (PHASE) senses the piston position.When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor (PHASE) provides various controls of engine parts instead, utilizing timing of cylinder identification signals.The sensor consists of a permanent magnet and Hall IC.When engine is running, the high and low parts of the teeth cause the gap with the sensor to change.The changing gap causes the magnetic field near the sensor to change.Due to the changing magnetic field, the voltage from the sensor changes.ECM receives the signals as shown in the figure.
Thanks. I understand all of that. But if you would refer to my original post, when the wave pattern of the CMP seems perfect when
running, where would you go next?
I would look at the cam shaft for condition
