Order of inspection
P0163 O2 Sensor Circuit Low Voltage (Bank 2 Sensor 3) Medium
The P0163 code means the third oxygen sensor on bank 2 is reporting a voltage below the minimum. It only appears on vehicles with three sensors per bank, usually those with two catalytic converters in series. Its spot under the vehicle makes the wiring the main suspect.
