OPERATION





The signal circuit of the camshaft sensor has a voltage of approximately 5V. The camshaft has a reluctor wheel bolted to the front of left exhaust camshaft, the camshaft signal is approximately 0V. This 0V to 5V signal is used by the Powertrain Control Module (PCM) 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.
