  • Page 49: Glossary

    Appendix A – 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. Ideally the A/F ratio is 14.7:1. ABS: Anti-lock Brake System.
  • Page 50 ® AutoScanner A device that interfaces with a vehicle to Read and Erase Diagnostic Trouble Codes through an OBD II data link. Bank x: The standard way of referring to the bank of cylinders containing cylinder #x. In-line engines have only one bank of cylinders. Most commonly used to identify the location of oxygen sensors.
  • Page 51 Closed Loop (CL): A feedback system that uses the O2 Sensor(s) to monitor the results of combustion. Based on the signal(s) from the O2 sensor(s), the PCM modifies the air/fuel mixture to maintain optimum performance with lowest emissions. In closed loop mode, the PCM can “fine tune” control of a system to achieve an exact result.
  • Page 52 Drive Cycle: Vehicle operation for a period of time so the systems can be monitored. DTC: Diagnostic Trouble Code. An alphanumeric identifier for a fault condition identified by the On Board Diagnostic System. Duty Cycle: A term applied to signals that switch between “on” and “off”. Duty cycle is the percentage of time the signal is “on”.
  • Page 53 EST: Electronic Spark Timing. An ignition system that allows the PCM to control spark advance timing. The PCM determines optimum spark timing from sensor information — engine speed, throttle position, coolant temperature, engine load, vehicle speed, Park/Neutral switch position, and knock sensor condition. EVAP: Evaporative Emissions System.
  • Page 54 IPC: Instrument Panel Cluster. ISC: Idle Speed Control. A small electric motor mounted on the throttle body and controlled by the PCM. The PCM can control idle speed by commanding the ISC to adjust its position. ISO: International Organization of Standardization also know as International Standards Organization.
  • Page 55 MAT: Manifold Air Temperature sensor. A resistance sensor in the intake manifold that sends a voltage signal to the PCM indicating the temperature of the incoming air. The PCM uses this signal for fuel delivery calculations. MIL: Malfunction Indicator Lamp. “Check Engine” or “Service Engine Soon” light are examples of what a MIL is called.
  • Page 56 Open Loop (OL): A control system mode that does not monitor the output to verify if the desired achieved results. A fuel delivery system will usually operate in open loop mode during cold engine warm-up because the oxygen sensors are not yet ready to send a signal. Without the oxygen sensor signal, the computer cannot check the actual results of combustion.
  • Page 57 QDM: Quad Driver Module. RAM: Random Access Memory. Relay: An electromechanical device in which connections in one circuit are switched. Reluctance Sensor: A type of sensor typically used to measure crankshaft or camshaft Speed and/or position, driveshaft speed, and wheel speed. ROM: Read-Only Memory.
  • Page 58 STFT: Short Term Fuel Trim. STS: Service Throttle Soon. TAC: Throttle Actuator Control. TBI: Throttle Body Injection. A fuel injection system having one or more injectors mounted in a centrally located throttle body, as opposed to positioning the injectors close to an intake valve port. Central Fuel Injection (CFI) is another name for TBI on some vehicles.
  • Page 59 Traction Assist: Assist in traction with brakes only. TTS: Transmission Temperature Sensor. A resistance sensor mounted in the transmission housing in contact with the transmission fluid. It sends a voltage signal to the PCM indicating the temperature of the transmission. VECI: Vehicle Emission Control Information.
