Appendix B—Glossary
A/C:
Air conditioner
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.
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
Accel:
Accelerator
Acssry:
Accessory
Actuator:
Actuators such as relays, solenoids, and motors allow
the PCM to control the operation of vehicle systems.
Air Injection Reaction (AIR) System:
