HVS Ignition Component Description

The following is a description of ignition system components and their functions.

CKP Sensor
The CKP sensor is located in the engine front cover perpendicular to a reluctor ring mounted on the crankshaft nose. The reluctor ring has 3 or 4 slots depending on whether the engine has 6 or 8 cylinders. As the reluctor rotates past the sensor tip, the slots change the sensor magnetic field to produce a voltage ON-OFF signal. Based on these signals, the PCM is able to determine crankshaft speed and position.

CMP Sensor (HVS) in Distributor
The CMP sensor is located in the distributor base. The distributor is driven by the camshaft and distributes the secondary voltage to the spark plugs through the distributor rotor, cap, and wires. The CMP sensor produces a signal once every revolution of the camshaft. The CMP signal identifies the position of the #1 cylinder relative to the crankshaft.
