Operation

This electronic ignition system is known as a High Voltage Switch (HVS) distributor ignition system. Trigger information is supplied only by the CKP sensor. The CMP HVS is located inside the distributor, and is used for fuel injector sequencing and misfire diagnosis. There is no back-up or by-pass system used, so the engine will not run without a valid CKP input. The PCM signals the coil to fire through the IC module. The resulting secondary energy is distributed to the spark plugs by a conventional distributor cap and rotor assembly.
