IAC:

Idle Air Control. A device mounted on the throttle body which adjusts the amount of air bypassing a closed throttle so that the PCM can control idle speed.

IAT:

Intake Air Temperature (Sensor)

ICM:

Ignition Control Module.

IMRC:

Intake Manifold Runner Control

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.

KAM:

Keep Alive Memory

Knock Sensor (KS):

Used to detect engine detonation or knock. The sensor contains a piezoelectric element and is threaded into the engine block. Special construction makes the element sensitive only to engine vibrations associated with detonation.

Knock:

Uncontrolled ignition of the air/fuel mixture in the cylinder. Also referred to as detonation or ping. Knock indicates extreme cylinder pressures or “hotspots” which are causing the air/fuel mixture to detonate prematurely.

KOEO:

Key On Engine Off. Turn the ignition key to on, but don’t start the engine.

KOER:

Key On Engine Running. Start the vehicle.

LCD:

Liquid Crystal Display

LTFT:

Long Term Fuel Trim

M/T:

Manual transmission or manual transaxle.

MAF:

Mass Air Flow (sensor). Measures the amount and density of air entering the C engine and sends a frequency or voltage signal to the PCM. The PCM uses this signal in its fuel delivery calculations.
