Code P1112 Jeep Description
The P1112 diagnostic trouble code for Jeep vehicles indicates an issue with the Intake Air Temperature (IAT) sensor circuit experiencing intermittent low voltage. The IAT sensor is responsible for monitoring the temperature of the air entering the engine, which is crucial for the proper functioning of the engine management system. When the voltage output of the IAT sensor falls below the specified range, it triggers the P1112 code. This can lead to a variety of performance issues as the engine control module relies on accurate temperature data to adjust fuel delivery and ignition timing.
