Hello,

P0138 †Oxygen Sensor Circuit High Voltage (Bank 1 Sensor 2)

Bank 1 is Driver Side

Sensor 2 is the downstream sensor, or the next sensor down. There is one in each exhaust manifold (sensor 1) and and depending on if your vehicle has 3 or 4 sensors they will be down by the catalytic converter(sensor 2)
