I have replaced the IAT sensor, charged my batteries, checked the wiring for any issues, and still cannot seem to get the sensor to read anything other than 260 degrees.

It's causing a P0111 code and causing the grid heater to no longer activate.

It's been single digits at night, and while I'm at work, it's become difficult to start the truck.

If I upload the stock file then reinstall the current tune, would it reset everything?

Or, would disconnecting the batteries work?

Or, since my batteries went into battery saver quite a few times before I installed the genius 2, do I need to replace batteries?

Does anyone got any suggestions?
