On a CAN bus, a frame is the basic unit of messaging. For a classic CAN bus, a frame consists of an 11-bit identifier along with an 8-byte message payload.
The only analog sensor in the system was the oxygen sensor. In other respects, it was a typical "feedback" carburetor system of the early-1980s, using a stepper motor to control fuel mixture and a two-stage "Sole-Vac" (which used a solenoid for one stage, and a vacuum motor for the other) to control idle speed.

A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...
