Code P0112 2013 Toyota RAV4 Description
The diagnostic trouble code P0112 for a 2013 Toyota RAV4 refers to the Intake Air Temperature Circuit Low Input. This code indicates that the Engine Control Module (ECM) has detected a lower than normal voltage signal from the Intake Air Temperature (IAT) sensor circuit. The IAT sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for determining the optimal air-fuel mixture for combustion.
Common Causes of P0112 2013 Toyota RAV4
- Faulty Intake Air Temperature (IAT) sensor
- Damaged wiring or connectors in the IAT sensor circuit
- Corrosion or poor connections in the sensor circuit
- Malfunctioning Engine Control Module (ECM)
- Intake air leaks near the sensor
Symptoms of P0112 2013 Toyota RAV4
- Decreased fuel efficiency
- Rough idling or engine hesitation
- Engine stalling
- Loss of power during acceleration
- Check Engine Light illuminated on the dashboard
