OPERATION

The camshaft position sensor provides fuel injection synchronization and cylinder identification.

The distributor does 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.

The distributor is held to the engine in the conventional method using a holddown clamp and bolt.

Although the distributor can be rotated, it will have no effect on ignition timing.

All distributors contain an internal oil seal that prevents oil from entering the distributor housing.

The seal is not serviceable.
