Operation
OPERATION
The signal circuit of the camshaft sensor 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.
