Code P0112 2015 Toyota RAV4 Description
The P0112 diagnostic trouble code (DTC) for a 2015 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 incoming air into the engine. This information is crucial for the ECM to adjust the air-fuel mixture for optimal combustion and performance. When the ECM receives a low voltage signal from the IAT sensor, it may not be able to accurately adjust the air-fuel mixture, leading to potential performance issues.
Common Causes of P0112 2015 Toyota RAV4
- Faulty intake air temperature sensor
- Wiring issues or a short circuit in the IAT sensor circuit
- Loose or corroded electrical connections
- ECM software or hardware issues
- Intake air leaks near the sensor
Symptoms of P0112 2015 Toyota RAV4
- Decreased fuel efficiency
- Rough idling or stalling
- Engine misfires
- Check Engine Light illuminated
- Reduced engine power
How to Fix P0112 2015 Toyota RAV4
- Diagnose the issue by using a scan tool to verify the P0112 code and check the IAT sensor's voltage reading.
- Inspect the wiring and connectors for any visible damage or corrosion. Repair or replace as needed.
- Test the IAT sensor's resistance and compare it to the manufacturer's specifications. Replace if necessary.
- Clear the DTC and reset the ECM to see if the code returns after repairs.
- Test drive the vehicle to ensure the issue has been resolved and monitor for any recurring symptoms.
Cost to Fix P0112 2015 Toyota RAV4
