Camshaft Position Sensor

The camshaft position sensor - intake and camshaft position sensor - exhaust is triggered by a notched reluctor wheel built onto the intake camshaft sprocket. The camshaft position sensor - intake and camshaft position sensor - exhaust provides four signal pulses to every camshaft revolution. Each notch, or feature of the reluctor wheel is of a different size which is used to identify the compression stroke of each cylinder and to enable sequential fuel injection. The camshaft position sensor - intake and camshaft position sensor - exhaust is connected to the ECM by the following circuits:

• A 5 V reference circuit
• A low reference circuit
• A signal circuit
