Question

bwm 530i 04 where to find the fuse in my car for the oxygen sensor for the code P0056?

Answer 1

HI there

The fuse is in the fuse box under the hood and should be labeled as the O2 sensor fuse. If the fuse is good, make sure the wiring on the bank 2 rear sensor isn't touching the exhaust, if it looks good, replace the sensor.
