14. • The Hall sensor (sometimes called the
Camshaft Position Sensor, CPS) is a
separate unit from the Crankshaft Position
Sensor (KPS), G28.
• The sensor is located at the end of the
camshaft for the cylinder head.
15. • The voltage supply to the Hall sensor is provided by the
MPI control unit.
• The signals from the reference sensor and the Hall
sensor are used to identify the ignition TDC of the
number three cylinder.
• When starting the engine, the first ignition and injection
points are triggered by the MPI control unit after receiving
both signals.

17. • The knock sensors make use of this phenomenon by
sending the ECU a signal at the onset of engine knock.
The sensor contains a Piezo electric element which,
when deformed by cylinder block vibration, infers that
detonation (knock) is occurring and informs the ECU by
generating a voltage. The ECU reacts to this signal by
retarding the ignition timing. Vigor engines have two
knock sensors. (See illustration at right for location.)
