Display Group 043

Current flank rise and/or flank fall time (response time) of voltage signal of heated oxygen sensors in front of three way catalytic converters

NOTE:
- When diagnostic conditions are fulfilled (display group 042) display group 043 shows the current flank rise and/or flank fall times. After diagnosis is ended, the diagnostic times shown are those that were recognized when the most recent diagnosis was carried out.
- If the limit values (flank rise time 90 ms/flank fall time 100 ms) are exceeded, the diagnosis is recognized as not OK. The flank rise and/or flank fall times now continue to be checked, while the display values in display group 034 are incremented with each additional test. However, the limit values can also be exceeded because of combustion misfiring being recognized. In this case, the malfunction "Bank X probe Y signal too slow" is not stored in DTC memory but "Cyl.x Combustion misfiring recognized" is stored.
