Display Groups 30-33, 99 (Oxygen Sensor (O2S) Control)

Measured value blocks, display groups 30...33, 99 - Oxygen Sensor (O2S) control, evaluating







Significance of characters in 3 digit number block, display zones 1 and 2 - Status of Oxygen Sensor (O2S) control before and after Three Way Catalytic Converter (TWC)







Display group 31 - Oxygen Sensor (O2S) control constantly operating Oxygen Sensors







Display group 32 - Oxygen Sensor (O2S) control - Oxygen Sensor (O2S) learned values before Three Way Catalytic Converter (TWC)







NOTE on display zones 1 and 2:
- Low values indicate that the engine is running too rich and therefore the Oxygen Sensor (O2S) control is leaning the mixture.
- High values indicate that the engine is running too lean and therefore the Oxygen Sensor (O2S) control enriches the mixture.
- If there is no voltage supply to the control module all the values learned will be reset. DTC memory, checking and erasing Reading Diagnostic Trouble Codes.
- add = additive - The effects of the malfunction (e.g. unmetered air) will reduce as the engine speed increases. The injection period will be modified by a fixed amount for additive learned values. This amount is not dependent upon the basic injection period.
- mul. = multiple active - The effects of the malfunction (e.g. faulty fuel injector) will increase as the engine speed increases. A multiple active learned value is a proportional change to the injection period. This change is dependent on the basic injection period.
