We keep getting this message. It doesn’t seem to affect anything but we clear it and it comes back. Seems to happen when I cut back on the throttle. It’s hard to see in the picture. However, the message reads: DTC 112: IAT VOLTAGE LOW; SPN 105 FMI 4

We have a 2014 G21 with the 409 engine.

Does anyone have any ideas on fixing this?

Thanks

Probably a bad sensor.
