P0112 2020 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.

What it means: P0112 2020 Honda CR-V indicates Intake Air Temperature Sensor 1 Circuit Low Voltage.
Common causes: 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: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0112 2020 Honda CR-V Description

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. IAT Sensor 1 resistance varies depending on temperature. The output voltage and the sensor resistance increase as the intake air temperature decreases. Conversely, the output voltage and the sensor resistance decrease as the intake air temperature increases. If the IAT sensor 1 output voltage is excessively low or high, the Powertrain Control Module (PCM) detects a malfunction and stores a Diagnostic Trouble Code (DTC).
