P0114 2017 GMC Sierra Code - Intake Air Temperature Circuit Intermittent
Quick Answer
The intake air temperature (IAT) sensor 1 is a variable resistor that measures the temperature of the air in the sensor bore. Common causes include Dirty air filter, Faulty Intake Air Temperature (IAT) Sensor, Intake Air Temperature Sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
