Truck started chugging especially when cold and engine light came on.Hooked up my scanner and found 02 sensor code.Purchased the part today but am unsure how to determine which sensor to change as I understand there are more than 1.

Bank one is on the driver side exhaust, bank two is on the passenger side exhaust. sensor one is ahead of the catalytic converter and sensor two is behind it toward the rear of the vehicle for both sides. So a bank one sensor one is the first one back from the motor on the drivers side
