Early TBI systems used an idle air control stepper motor.
Early carburetor-based systems used a programmable throttle stop using a bidirectional DC motor. Idle speed is controlled by a programmable throttle stop or an idle air bypass control stepper motor. The engine RPM is monitored by the crankshaft position sensor which plays a primary role in the engine timing functions for fuel injection, spark events, and valve timing. Most engine systems have idle speed control built into the ECU. The ECU controlling an automatic transmission would simply downshift the transmission if this were the cause of knock/ping.

In this case the knock/ping results from the piston not being able to move downward as fast as the flame front is expanding, but this latter mostly applies only to manual transmission equipped vehicles. A second, more common source of knock/ping is operating the engine in too low of an RPM range for the "work" requirement of the moment. If the ECU detects knock, a condition which is potentially destructive to engines, and "judges" it to be the result of the ignition timing being too early in the compression stroke, it will delay (retard) the timing of the spark to prevent this. An ECU can adjust the exact timing of the spark (called ignition timing) to provide better power and economy. Mixture control on computer controlled carburetors works similarly but with a mixture control solenoid or stepper motor incorporated in the float bowl of the carburetor.Ī spark ignition engine requires a spark to initiate combustion in the combustion chamber. If the engine has not warmed up yet, more fuel will be injected (causing the engine to run slightly 'rich' until the engine warms up). The ECU will inject more fuel according to how much air is passing into the engine. If the throttle pedal is pressed further down, this will open the throttle body and allow more air to be pulled into the engine.
