UEGO zero calibration indicates the stoichiometric point of the internal wideband controller. Adjust this value with the wideband O2 sensor unplugged from the wideband cable. If the AFR display indicates more than 14.7 AFR, reduce the UEGO zero calibration value. If the AFR display indicates less than 14.7 AFR, increase the UEGO zero calibration value.
UEGO gradient calibration indicates the free air point of the internal wideband controller. Adjust the UEGO zero calibration value before adjusting this value. Pull the wideband O2 sensor from the tailpipe and plug it into the wideband cable. Turn the ignition power on and allow several minutes for the sensor to heat up and reach operating temperature. If the AFR display indicates more than 21.5 AFR, reduce the UEGO gradient calibration value. If the AFR display indicates less than 21.5 AFR, increase the UEGO gradient calibration value. Use the smallest value that will display a constant 21.5 AFR.
