    I've gotta be doing something wrong.

    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.
    Just a frost bitten Canadian.

    The grand prixs dont have a bank 2.

    You need to swap that for a bank 1 sensor 2 to read the o2 sensor after the cat.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
