Hi, I could use a little help. Car is 2002 H6 UK spec, 70k miles.
CEL came on, along with 'VDC off' light. I pulled a P0151 code: O2 sensor circuit low voltage bank 2 sensor 1. I've done the obvious and checked the connection from the front O2 sensor to the loom, and checked for vacuum and exhaust leaks. Is this likely to be as simple as a sensor replacement, or are darker forces at work here, and why the 'VDC off' light? It clears if I stop the engine and restart. There's only the one code, but I could log the fuel trim values if that would be useful. Any suggestions as to what the problem might be are most welcome!
