P1160 MINI MeaningShort term fuel trim (STFT) is a value that indicates how the Engine Control Module (ECM) is adapting the factory programmed fuel map. The fuel map is a lookup table that is referred to by the controller. This is used to govern the correct amount of fuel to inject. This amount depends on the speed and load conditions monitored on the vehicle. The (STFT) Value alters depending on which fuel map load cell the engine is operating during speed and load conditions.
The oxygen sensor is a key part of the fuel trim calculation. If the Oxygen sensor indicates a lean mixture, the (STFT) will be increased above the typical Value. If the Oxygen Sensor indicates a rich mixture the (STFT) will be reduced below the typical Value. In normal operation, the fuel trim values will cycle between a maximum of 10 and -10%. (STFT) which exceed this Value should be investigated.
