HO2S Bank 1 and Bank 2 Sensor 1
The scan tool displays a range of
0-1,106 mV. The
HO2S Bank 1 and Bank 2 Sensor 1 parameter represents the fuel control 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.
