HO2S Bank 1 and Bank 2 Sensor 2

The scan tool displays a range of 0-1,106 mV. The HO2S Bn1 and Bn2 Sensor 2 parameter represents the exhaust oxygen sensor output voltage. The voltage fluctuates constantly within a range between 10 mV (lean exhaust) and 1,000 mV (rich exhaust) while operating in Closed Loop.
