Camshaft Position Sensor: Description and Operation
Distributor
PURPOSE
The Camshaft Position (CMP) sensor detects the Number 1 cylinder when it reaches Top Dead Center (TDC) and signals the Powertrain Control
Module (PCM) to control fuel injection amount, timing and fuel pump circuit.
OPERATION
A single vane rotor cap spins according to camshaft speed. As it rotates through a magnetic Hall Effect pickup switch, the sensor detects the
opening on the rotor cap and sends an input signal to the PCM.
