Boxster (986) F6-2.5L (1998)
Camshaft Position Sensor: Description and Operation
HALL SENSOR:
A new, plug-in, plastic covered Hall sensor used to determine the ignition TDC of the 1st cylinder is installed at the 3rd cylinder in the camcase for
cylinder line 1 - 3.
The Hall signal is generated by a rotor which is attached to the intake camshaft for cylinder line 1 - 3.
Apart from determination of the ignition TDC of the 1st cylinder and the associated assignment of the injection signals (sequential), the ignition signals
(permanent high-voltage distribution), and the knock sensor signals (knock control), the Boxster's Hall sensor signal is also used for diagnosis in the
VarioCam system.
