I hope someone can help. The engine light has come on, I've connected a friend's obd and there's two errors, both are p0131 "02 sensor circuit low voltage bank1 sensor1" does this mean I need a new lambda sensor?? Thanks in advance. John

Hi yes normally O2 sensors need changing every 80k or five years if yours is the original I think you can safely say its had its fun.

Hi John , That's the one or you can remove and clean the one that's in  Jasonj

 

Thanks, I didn't realise cleaning them was an option. I'll look into this before I buy a new one.
