When you see the Engine Light ON or the Service Engine Soon Warning Light, it could be due to fault code P1112. This code indicates an issue with the Intake Air Temperature (IAT) sensor circuit. The IAT sensor is responsible for measuring the temperature of the incoming air into the engine.

A faulty IAT sensor can cause various problems, such as incorrect fuel mixture, reduced engine performance, and increased emissions.

It can also lead to difficulties in starting the vehicle and poor fuel efficiency.

To fix this issue, you should first check the wiring and connections of the IAT sensor. Look for any loose or damaged wires that may be causing the problem. If the wiring is fine, then the IAT sensor itself may need to be replaced.

It is important to address this issue promptly to ensure optimal engine performance and fuel economy.

What are the possible causes of fault code P1112 in an automobile?

The fault code P1112 in an automobile can be caused by a faulty Intake Air Temperature Sensor, an open or shorted sensor harness, a poor electrical connection in the sensor circuit, or a damaged Powertrain Control Module (PCM).
