P1112 KIA Code - Intake Air Temperature Sensor Circuit Intermittent Low Voltage
Quick Answer
The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. Common causes include Faulty Intake Air Temperature Sensor, Intake Air Temperature Sensor harness is open or shorted, Intake Air Temperature Sensor circuit poor electrical connection. 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.
