For example HO2S11 would be the oxygen sensor on bank 1 and first in line (pre catalytic converter) and HO2S12 would be on bank 1, but second in line (the monitor) An oxygen sensor creates a voltage between 0 and 1 volt by means of a chemical reaction between the sensor element and the oxygen in the exhaust passing across that element. 9 5-Wire Wideband Oxygen Sensors 17025 The Bosch LSU 4 wideband oxygen sensor is a 5-wire sensor that reads oxygen in much the same way as a traditional oxygen sensor. Sensor 1 would be the pre-cat, or upstream, or the O2 sensor closest to the cylinder head. In other words, you don't need a scan tool with live data capability to see if the front oxygen sensor is working or not. 200 matches. Thus while it is possible (but illegal I think) to bypass the converters, you check engine light will remain on, and you computer will be misled and continually provide the wrong fuel mix. 7:1 air fuel ratio (AFR).
