I replaced the Front Heated Oxygen sensor for a used one (due to cash..) the readout of my old sensor was idle (and warm) around 40, but had cutouts. After change I did new readout, idle around 12-15. My question is: What should a good working Oxygen sensor readout (ECM) be? I have the feeling that the fuel consumption is higher after change.
Car: XC70 AWD D5 136kw 2006.
Any input is very much appreciated.
In a later stadium I will tell all about fitting a LPG-system (STAG) in my Diesel. I went from 7.6/100 -> 5.3/100 adding LPG. But that later!
