If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory diagnostic trouble code (DTC) is stored.

One example of this would be when an automatic vehicle in placed in gear.

Note that the idle air control valve is closed by the PCM when the throttle plate is opened to prevent excess air from entering the engine.
