Short Term FT
Range 0-255 (-100 Percent to 100 Percent): Short Term FT represents a Short Term correction to fuel delivery by the
PCM in response to the amount of time the
oxygen sensor voltage spends above or below the
450 mV threshold. If the oxygen sensor has mainly been below
450 mV, indicating a lean
air/fuel mixture, Short Term FT will increase to tell the PCM to add fuel. If the oxygen sensor voltage stays mainly above the threshold, the PCM will reduce fuel delivery to compensate for the indicated rich condition.
