Code P1112 2000 Ford F150 Description

The P1112 diagnostic trouble code (DTC) for a 2000 Ford F150 indicates an intermittent issue with the Intake Air Temperature (IAT) sensor. The IAT sensor is a crucial component of the engine's air intake system, responsible for measuring the temperature of the incoming air. This information is used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion efficiency. An intermittent fault with the IAT sensor can lead to incorrect temperature readings being sent to the ECM, resulting in poor engine performance, reduced fuel efficiency, and potential drivability issues.
