I did a search to help me figure the P1652 code. Can anyone respond with a decent interpretation of the code. I have seen it as a "IAC monitor disabled by PSP switch failed on" and also something to do with J1850 communications bus. I am just wondering if it is something important to go to the dealer with or just something I can clear with no problem with my Autotap software.

Thanks

I tried it on my OBD II software and shows it being:

"Manufacturer Control Auxiliary Inputs Auxiliary Outputs"

Don't know if this helps any, but it's what I found.

Thanks for the reply, I searched on the open web for almost 2 hours and really found nothing that would make me believe it is something major. I just used my Autotap software and erased the code. I am not sure if it was because I was lugging it on base today going 25 and not taking out of OD. Running at 700 RPM's might have triggered the code, not sure but I am going to be monitoring it.

I would clear it and see if it comes back, if not don't worry about it. If it does than I would take it in.
