    Windband issue- gauge works, HPT flatline

    Hey guys, can someone try to point me in the right direction to fixing this please? PLX wideband, gauge reads good but in my scans the AFR is flat at 14. I'm guessing its a wiring issue but looking for other opinions before I start tearing things apart. Thanks!

    Looked at the log more closely and tested a new one. Its not a flat line but is very close. I checked wiring and its good. I think my sensor may be fried from the Sunoco 110.....
