P0159 O2 Sensor Circuit Slow Response (Bank 2 Sensor 2) Low
The P0159 code means the bank 2 sensor 2 oxygen sensor is responding too slowly to changes in the air-fuel mixture. The usual cause is an aging or contaminated sensor, although exhaust leaks and mixture problems can do it too. It rarely affects how the car drives, but it will keep you from passing an emissions test.
