P0112 2021 Honda CR-V Code - Intake Air Temperature Sensor 1 Circuit Low Voltage
Quick Answer
The Intake Air Temperature (IAT) Sensor 1 is a thermistor that detects intake air temperature, and it is used for air/fuel ratio feedback control to compensate for the atmospheric density fluctuations that accompany changes in intake air temperature. Common causes include Faulty Intake Air Temperature (IAT) Sensor 1, Intake Air Temperature Sensor 1 harness is open or shorted, Intake Air Temperature Sensor 1 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.
