HHO Abbreviations

The following are the abbreviations the auto industry use which may help you in your journey thru HHO.
AFS: Air/Fuel Ratio Sensor.

CEL: Check Engine Light. The engine trouble light, that lights up on your dash when the ECU detects an irregularity.

COP: Coil  On Plug. A type of ignition system that doesn’t require spark plug wires, and has a coil mounted directly to each spark plug.

CTS: Coolant Temperature Sensor.

DIS: Distributor less Ignition Systems. Systems that use electronics instead of a  standard distributor to calculate spark timing.

DTC: Diagnostic Trouble Code. The code number that the ECU gives you to help diagnose an error condition. For 1996 and newer vehicles, these can be read by standard OBD-II readers. Older vehicles may have a system for initiating a blink code, whereby the error numbers are read by the number of blinks of the Check Engine Light.

ECM: Engine Control Module.  See ECU.

ECT: Engine Coolant Temperature sensor.

ECU: Engine Control Unit. The  ECU is the most common name for the cars computer.

EFI: Electronic Fuel Injection.

EFIE: Electronic Fuel Injection Enhancer. The efie is installed to trick the  signal from an oxygen sensor this will make the

ECU l lean the fuel mixture.

EOP: Engine Oil Pressure sensor.

IAT: Intake Air Temperature sensor.

MAF: Mass Air Flow sensor. Measures the amount of air flowing into the engine.

MAP: Manifold Absolute Pressure sensor. Measures the pressure inside the intake manifold. The ECU compares this to the barometric pressure sensor (outside air pressure) to determine the difference between the pressure in the manifold and the outside air.

MAT: Manifold Air Temperature.

O2S: Oxygen Sensor.
