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.
Ideally the A/F ratio is 14.7:1.
ABS:
Anti-lock crake system
A/C clutch relay:
The PCM uses this relay to energize the A/C clutch,
turning the A/C compressor on or off.
A/C pressure sensor:
Measures air conditioning refrigerant pressure and
sends a voltage signal to the PCM.
A/C pressure switch:
A mechanical switch connected to the A/C refrigerant
line. The switch is activated (sending a signal to the
PCM) when the A/C refrigerant pressure becomes too
low or high.
Actuator:
Actuators such as relays, solenoids, and motors allow
the PCM to control the operation of vehicle systems.
Air Injection Reaction (AIR) System:
An emission control system operated by the PCM. Dur-
ing cold starts, an air pump injects outside air into the
exhaust manifold to help burn hot exhaust gases. This
reduces pollution and speeds warm-up of oxygen sen-
sors and catalytic converters. After the engine is warm,
the air will either be dumped back to the atmosphere (or
into the air cleaner assembly) or sent to the catalytic
converter.
APP:
Acceleration pedal position (sensor)
ASR:
Acceleration slip regulation
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. See O2S, Sensor x, Sensor
x.
BARO:
Barometric pressure sensor. See MAP sensor.
BBV:
Brake boost vacuum (sensor)
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:
