    IAT lo code 23

    How do I disable this code? I don't have an intake air sensor and my CTS/IAT blend tables are all set to 100%. I'm trying to eliminate this as a potential cause of being unable to go into closed loop.

    Before you ask, I did uncheck the boxes that enable code 23 & 25

    My only other suspect is that I connected the brown wire from the LC-2 wideband to the first connector labeled 0 on the ECM, assuming it was for the narrow band reading. It only measures .10 to 1.1 volts between 14 & 15 AFR. I noticed the factory settings were 1.1 @ 14 & .10 @ 15. That seems backwards to me. Am I wrong?

    The yellow wire is connected to the #1 connector and it appears to work the way it should.
