Hi, can you help?

My honda ( uk spec model ith 4ws ) is showing the fault code for the o2 sensor, can you tell me is the o2 sensor fused and if it is, Where do i find the fuse?
The sensor itself is mounted in the exhaust before the cat.

Hi dniezgoda,

There is no fuse for the O2 sensor.
The heated circuit gets its power from the ignition switch.

You need to replace the sensor if it is faulty.
