    Default Reading transducer data with a 411 PCM

    I'm working on a 2000 Chevy S-10 that has a 411 PCM swapped in. The PCM is using a (2002 S-10) OS12212156. The stock 2002 does not have an EGR or a AC pressure sensor. I have never been able to read the EGR pintle voltage with the EFI scanner. The EGR is wired correctly. It appears as though the PCM is just not able to read this input. (Like it is disabled.)
    Is there a way to get the scanner to read the EGR signal (blueConn-pin55)?

    If the EGR won't work,.. Is there a way to read the transducer from the AC pressure sensor input? That is, is there a way to enable that line/operation for the 411 PCM? (What PCM pin does the AC pressure sensor go to?)

    Is there another way to read transducer data without doing some custom wiring?

    Thank you

    Do you have the EGR enabled in the tune?

    I don't know.
    This sounds like what I am asking about. That is, I'm not aware this can be done, or where/how to do it.
    I will need to go looking for it.
    Thanks
