02 Sensor problems

[Tuppence]

I have just had the 02 sensor P0138 circuit high voltage,(bank 1 sensor2) replaced.  VSC and engine light and traction light on since Xmas.  Difficulty finding honest mechanic and with right equipment near me.  (France) Toyota/Lexus definately not honest so can't go there.  Immediately lights are still the same, now code is P0031 Bank 1 Sensor 1

Can't really deal with this now till May, what does this sensor do?  Can I use car safely or can I damage it?  Don't do many miles.

You may find yourself using more fuel, and in the long term it's not good for the engine.  As far as I'm aware, bank 1 sensor 1 can be done from the top so a fairly easy job that only needs a sensor socket, about £10 from eBay. I'm sure it's the same as the GS300 which I did last year from the top, in other words no need to crawl under the car or raise it up.
