Intake air temperature is different than an O2 sensor...one is on the intake side and one is on the exhaust side...

I had the same code, removed both sensors on the charge pipe and intake manifold, cleaned them with brake cleaner and cleaned the connections with wiring contact cleaner. no more codes
