P0138 code - Peugeot 207
Discussion
Had a P0141 code (O2 Sensor Heater Circuit Malfunction Bank 1, Sensor 2). Changed the oxygen sensor which was in a bad way and that has been resolved.
Now I am left with a P0138 code (O2 Oxygen Sensor Circuit High Voltage Bank1, Sensor2) but am unsure what the problem could be.
Engine idles rough and there is a strong smell of petrol when I first start the car.
I must add the 'depollution system faulty' message has appeared for at least 6 months and I have ignored it like an idiot and now I'm paying the price.
Any ideas?

I had a mechanic look at it yesterday and he basically said the same as you and advised me to buy a Bosch one.
Showed me the voltage readings, the upstream one was fluctuating a lot between 0.1 - 0.9V whereas the downstream one (that I'd changed) was steady at 0.9V. He said it should also be fluctuating.
So I've bought a Bosch one, will change it tomorrow and hopefully it will solve the problem!
