    Scanner not reading AC pressure voltage

    Hello, I am tring to add wide band to AC. The problem is it will not read the voltage coming from the wide band. AC pressure stays at zero. I am using pin #11 on the red c2 connector. This is my ECM info. Any help would be appreciated. Thanks.
    ECM: 10, VPW
    VIN: 2GCEK19T8Y1103511 - 2000 Chevrolet Silverado 1500, 5.3 L, 8 Cyl, GM_P01
    Serial: 2DG0KH969203

    I use the EGR circuit myself, it's was easier because I kept my AC working.
    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.
