Fuse for O2 Sensor?
« on: July 22, 2019, 09:44:44 AM »
Can anyone tell me which fuse relates to the O2 sensor? I have a fault code P0030 I think it is. It is on a fairly new O2 Sensor only recently replaced. I believe wiring might be the issue. I wasn't able to detect 12v from the wiring going to the sensor. Want to check it's not the fuse first.
