When I connect my scanner to my 2005 Grand Prix, it shows 0 mv. for B2S1 [the rear sensor?].
The front sensor shows up just fine,as does everything else.
This is using the default HPT screen for my car - 3800 non s/c .... VIN 2.
The HPT version is the latest download and I'm running WIN 7,if that makes a difference.
When I connect up my buddy's Snap On Varus scanner,the rear O2 shows up just fine.
It looks like I need to change a setting.
Any ideas on what to do?
Thanks in advance.
