Appendix B – Glossary A/C: Air Conditioner A/D: Analog to Digital A/F: Air/Fuel ratio. The proportion of air and fuel delivered to the cylinder for combustion. For example, an A/F ratio of 14:1 denotes 14 times as much air as fuel in the mixture.
Glossary BCM: Body Control Module Boost Control Solenoid: A solenoid that is energized by the PCM, in order to control turbo/supercharger boost pressure. Brake Switch Signal: An input signal to the PCM indicating that the brake pedal is being pressed. This signal is typically used to disengage Cruise Control systems and Torque Converter Clutch (TCC) solenoids.
Glossary EFI: Electronic Fuel Injection. Any system where a computer controls fuel delivery to the engine by using fuel injectors. EGR: Exhaust Gas Recirculation. The PCM uses the EGR system to recirculate exhaust gases back into the intake manifold to reduce emissions. EGR is used only during warm engine cruise conditions.
Glossary MAP: Manifold Absolute Pressure (sensor). Measures intake manifold vacuum or pressure and sends a frequency or voltage signal (depending on sensor type) to the PCM. This gives the PCM information on engine load for control of fuel delivery, spark advance, and EGR flow. MAT: Manifold Air Temperature (sensor).
Glossary ROM: Read-Only Memory. Permanent programming information stored inside the PCM, containing the information the PCM needs to operate a specific vehicle model/engine combination. RPM: Revolutions Per Minute SAE: Society of Automotive Engineers. Scan Tool: A device that interfaces with and communicates information on a data link. SDM: Sensing and Diagnostic Module Sensor x:...
Glossary Warm-up Cycle: Warm-up cycle is when the engine coolant temperature rises at least 40 degrees above that at engine start up. WOT: Wide-Open Throttle. The vehicle operating condition brought about when the throttle is completely (or nearly) open. The PCM typically delivers extra fuel to the engine and de-energizes the A/C compressor at this time for acceleration purposes.
