P1193 RAM Code - Inlet Air Temperature Sensor Circuit High Condition
Quick Answer
The Inlet Air Temperature (IAT) Sensor is a 2-wire thermistor, as intake air temperature increases, thermistor resistance, and signal voltage decrease. Common causes include Faulty Inlet Air Temperature (IAT) Sensor, Inlet Air Temperature Sensor harness is open or shorted, Inlet 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.
