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.

KOER:

Key On — Engine Running.

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 engine and sends a frequency or voltage signal to the

PCM. The PCM uses this signal in its fuel delivery calculations.

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.
