What is a obd 2 code po 113?

OBD-II code P0113 indicates a problem with the intake air temperature (IAT) sensor circuit, specifically that the sensor is reading a high voltage signal. This typically suggests that the sensor is either faulty, has a poor connection, or is experiencing a wiring issue. The IAT sensor measures the temperature of the air entering the engine, and a malfunction can affect engine performance and fuel efficiency. Diagnosing the issue often involves checking the sensor, wiring, and connectors for faults.
