Display Groups 30-44, 99 (Oxygen Sensor Control)

Measuring value blocks, evaluating display groups 30-44, 99 (oxygen sensor control)


Display group 30 -status oxygen sensor control-







Explanation of 3-digit value in display field 1:







Display group 32 -oxygen sensor control- oxygen sensor adaptation values







Evaluation display group 32, display field 1 through 4- oxygen sensor adaptation values












Display group 33 -oxygen sensor control- oxygen sensor control values












Oxygen sensor voltage U (lambda) in mV

A: Oxygen sensor voltage high
- rich mixture (excess fuel or too little oxygen)
- high CO value
B: Oxygen sensor voltage low
- lean mixture (too little fuel or excess oxygen)
- low CO value

Evaluation display groups 3, display fields 1 and 3 - oxygen sensor control bank 1 and 2







Evaluation display groups 4, display fields 2 and 3 - oxygen sensor voltage bank 1 and 2







Display group 34 -oxygen sensor control- diagnostic of oxygen sensor before catalytic converter bank 1 (aging test)







Display group 35 -oxygen sensor control- diagnostic of oxygen sensor before catalytic converter bank 2 (aging test)







Display group 41 -oxygen sensor heating before and after catalytic converter bank 1-







Display group 42 -oxygen sensor heating before and after catalytic converter bank 2-







Display group 43 -oxygen sensor control- diagnostic of oxygen sensor behind catalytic converter bank 1 (aging test)







Display group 44 -oxygen sensor control- diagnostic of oxygen sensor behind catalytic converter bank 2 (aging test)







Display group 99 -oxygen sensor control- operating condition oxygen sensor control
