iii. Camshaft Position Sensor :
Component Details :
A typical Hall Effect Sensor has three
wires or terminals: one for ground, one for
supply or reference voltage and one for the
output signal. To produce an output signal, a
Hall Effect Sensor must be supplied with a
reference voltage. When a metal/wheel
passes through the air gap between the
magnetic field (Magnet) and silicon chip (CAM
sensor), it blocks the magnetic field and
causes the chip’s output voltage to suddenly
drop to zero else the chip's output voltage is
4.7 Volts.
Component Location :
The cam phase sensor is mounted on
cylinder head cover
Preliminary Checks :
1. Loose / Damaged connections between
sensor and EMS ECU.
2. Check for back out of pins at both sensor
connector and ECU connector.
3. Check for damage of pins at both sensor
connector and ECU connector.
4. Check the continuity from sensor
connector pins to the ECU pins.
5. Physical damage to Cam target wheel.
6. Improper air gap between sensor and
cam target wheel.
