$14 Oxygen sensor signal, bank 1, sensor 1
Output of oxygen sensor voltage and associated oxygen sensor.
Display of sensor voltage between 0 V and 1.275 V and of the oxy-
gen sensor in percent.
In the case of decimal output, conversion factor = 0.005 (voltage of
oxygen sensor)
Decimal value displayed multiplied by 0.005 gives the voltage of
oxygen sensor.
Oxygen sensor display:
Lean to -100 %
Rich to 99.22 %
In the case of decimal output, conversion factor = 0.78125
Offset = -100 %
Decimal value displayed multiplied by 0.78125 minus 100% gives
the HO2S integrator.
$15 Oxygen sensor signal, bank 1, sensor 2
Output of oxygen sensor voltage and associated oxygen sensor.
Display of sensor voltage between 0 V and 1.275 V and of the oxy-
gen sensor in percent.
In the case of decimal output, conversion factor = 0.005
Decimal value displayed multiplied by 0.005 gives the voltage of
oxygen sensor.
