Distributor: Description and Operation

Distributor And Camshaft Position Sensor - Typical:

All engines are equipped with a camshaft driven mechanical distributor containing a shaft driven distributor rotor. All distributors are equipped with an internal camshaft position (fuel sync) sensor. This sensor provides fuel injection synchronization and cylinder identification.

The distributor do not have built in centrifugal or vacuum assisted advance. Base ignition timing and all timing advance is controlled by the powertrain control module (PCM). Because ignition timing is controlled by the PCM, base ignition timing is not adjustable on any of these engines.

All distributors contain an internal oil seal that prevents oil from entering the distributor housing. The seal is not serviceable.
