MM3 Tuner - EGT Display Reading?

[1badcobra]

In August, I installed an MM3 tuner and a brand-new EGT sensor kit on my 2016 2500.

It has been working great up until the outside temperatures have gotten cooler.

When the truck is started cold, the MM3 reads NA for the EGT.

After the truck warms up, I can shut it off and restart it, and then the sensor will start reading most of the time.

I've had a few times when it won't read.

Also, at times, driving down the road, the MM3 read would hang up at different temperatures until I shut the truck off and then back on.

I have checked the connections, and everything is tight.

Has anyone else experienced this?
