Malfunction Threshold
- High output performance monitor
The voltage of front secondary HO2S (bank 2, sensor 2) during the catalyst neutralization is less than 0.62 V for at least 22 seconds.
- Low output performance monitor
The voltage of front secondary HO2S (bank 2, sensor 2) during the fuel cut-off is more than 0.3 V for at least 6 seconds.
