Hi, does anybody have picture of pre-cat oxygen sensor pinout.
Got check engine light and an error code p2626. Found out, that there was no information coming from pre-cat oxygen sensor. Before replacing it, connected a new one, but still no signal...

 

What are you using as a scan tool/software? My OBD2 scanner software (Torque Lite) doesn't show a reading, but Torque Pro provides more info, although not voltage, only an equivalence ratio.
I just performed a replacement of both sensors.

 

what is your email? I’ll send you an invite to what you will need.

 

Did you ever find the problem with the o2? I'm having same problem. Sets code 2A99 for the upstream o2 signal wire.
