I am using a Rev built MS.

I replaced the intercooler charge piping last week and now the IAT sensor is always showing 70F in tunerstudio.

Even when it is unplugged it continues to show 70F. Before it would drop to -40, so I am wondering if anyone has seen this behavior before.

I have tested with several other GM IAT sender, but it is the fact that even when it is unplugged is making me think there is something somewhere else, I have gone over my engine bay several time, i am unaware of any other loose connectors that I forgot

 

70 means it's not working or the MS is not getting any signal from it, it defaults to that value.
