Camshaft Position Sensor: Description and Operation
PURPOSE
The crankshaft angle sensor produces an output pulse to the ECU 1 time per distributor rotation. The ECU uses this signal to determine TDC
position for #1 cylinder.
LOCATION
The sensor is mounted inside the distributor.
CONSTRUCTION
The sensor is made up of a pick-up coil and a rotor with 1 tooth coresponding to #1 cylinder TDC.
OPERATION
Whenever the engine is rotating, a sine-wave signal is returned to the ECU. As engine speed increases the frequency of the signal increases as
well. When coupled with the signal of the engine rpm sensor, exact piston position can be determined by the ECU.
