The first parameter is "Fuel Alcohol Content" displayed as a percentage. If the Fuel Alcohol Content percentage is above 25%, this is the
probable cause of DTC P0172.
-
From this screen the "Fuel Alcohol Content" can be reset to zero by pressing the lower right Tech 2(R) button. It will then display 0% when it's
reset. Finally, reprogram the PCM with the latest calibration. This will correct for the PCM alcohol calculations.
Note
The PCM must be reset from this screen. It does not reset to zero when the PCM is reprogrammed.
