I look under the car and see four air sensor. Two in front of the cat and two behind the cat which one of these for is sensor 134 right bank side.

P0134 is bank 1 (driver) and sensor 1 (front) no activity.... check to make sure it is plugged in... also depending on the mileage it may need changed. If you change it, buy 2 one for each side front.
