P0137 Code, Location of Sensor
Can anyone tell me where the O2 sensors are on the 2015+ WRX. Today I've thrown the P0137 code 3 times, so I think its time for a replacement, but not sure where the sensor is located.
TIA Michael

The turbo sits in the front, and is mounted lower, around the same height as the oil pan. The easiest way to find the sensor is remove the plastic skid tray, it’s just a bunch of pop clips, and follow the exhaust back from the turbo. The catalytic converter is pretty much right off the turbo hot side, and there’s two sensors on the exhaust, the upstream and downstream o2 sensors. The upstream (front) o2 sensor is located in the exhaust before the catalytic converter, it has a black plug. The downstream (rear) is located after the catalytic converter, and has a green plug. The o2 sensor can be removed with a 7/8” wrench.
