Camshaft Position Sensor: Description and Operation
Camshaft Position Sensor
Description
DESCRIPTION
The camshaft position (CMP) sensor (3) is mounted on the right cylinder head cover. The camshaft position sensor is a hall effect sensor, and supplies a
signal to the Electronic Control Module (ECM). The ECM uses the signals sent by the CMP and the crankshaft (CKP) sensor to determine injection
timing.
Operation
OPERATION
The signal circuit of the camshaft position sensor (3) has a voltage of approximately 5V. If the segment machined into the intake camshaft sprocket is
positioned opposite the camshaft sensor, the camshaft signal is approximately 0V. This 0V to 5V signal is used by the engine control module (ECM) for
detecting ignition TDC of cylinder 1 as the engine rotates. If no signal is supplied by the camshaft position sensor, the vehicle will not start.
