Code P0112 Hyundai Description
The P0112 diagnostic trouble code for Hyundai vehicles indicates a problem with the Intake Air Temperature Sensor 1 Circuit, specifically a low input signal. The Intake Air Temperature (IAT) sensor is responsible for measuring the temperature of the air entering the engine. This information is crucial for the engine control module (ECM) to adjust the air-fuel mixture and ignition timing for optimal performance and fuel efficiency. When the ECM detects a low input signal from the IAT sensor, it can lead to various issues affecting the vehicle's performance.
Common Causes of P0112 Hyundai
- Faulty Intake Air Temperature (IAT) sensor.
- Damaged or corroded wiring/connectors.
- Issues with the Engine Control Module (ECM).
- Air intake system leaks.
- Incorrect air-fuel mixture due to sensor malfunction.
Symptoms of P0112 Hyundai
- Check Engine Light illuminated on the dashboard.
- Decreased fuel efficiency.
- Rough idling or stalling.
- Loss of power or acceleration.
- Engine running too rich or too lean.
How to Fix P0112 Hyundai
- Begin by locating the Intake Air Temperature (IAT) sensor in the air intake system.
- Inspect the sensor, wiring, and connectors for any visible damage or corrosion.
- Test the IAT sensor using a multimeter to check for proper resistance values.
- Replace the IAT sensor if it is found to be faulty.
- Clear the diagnostic trouble codes using an OBD-II scanner and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0112 Hyundai
The cost of repairing a P0112 code on a Hyundai vehicle can vary depending on the specific model and year. On average, the cost of replacing an Intake Air Temperature (IAT) sensor ranges from $50 to $150. Labor costs at auto repair shops typically range from $80 to $150 per hour. Additional costs may include diagnostic time and any other necessary parts or repairs. It is recommended to consult with a qualified mechanic or dealership for a more accurate estimate based on your vehicle's specific needs.
