Malfunction Threshold

Either of the condition continues for at least 5 seconds: 

• The rear secondary HO2S (bank 1, sensor 2) output voltage (voltage difference between SO2B1 and SO2SGB1 terminals) is 1.42*1 (3.28)*2 V or more.
• The SO2SGB1 terminal voltage is 3.65*1 (3.47)*2 V or more.

*1 : 6-Speed A/T

*2 : 9-Speed A/T
