Code P1112 2010 Ford Fusion Description
The P1112 diagnostic trouble code (DTC) for a 2010 Ford Fusion indicates an intermittent condition with the Intake Air Temperature (IAT) sensor. The IAT sensor is a crucial component of the vehicle's engine management system, as it measures the temperature of the air entering the engine. This information is used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion and performance. An intermittent condition with the IAT sensor means that the sensor is not providing consistent or accurate temperature readings to the ECM, which can lead to various performance issues.
Common Causes of P1112 2010 Ford Fusion
- Faulty Intake Air Temperature (IAT) sensor
- Damaged wiring or connectors leading to the sensor
- Corrosion or contamination affecting sensor readings
- ECM software issues
- Environmental factors affecting sensor performance
Symptoms of P1112 2010 Ford Fusion
- Decreased fuel efficiency
- Rough idling or engine hesitation
- Engine stalling
- Check Engine Light illuminated
- Reduced engine performance
How to Fix P1112 2010 Ford Fusion
- Begin by locating the IAT sensor in the intake air duct or manifold.
- 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.
- If the sensor is faulty, replace it with a new OEM or high-quality aftermarket sensor.
- Clear the DTC and perform a test drive to ensure the issue has been resolved.
Cost to Fix P1112 2010 Ford Fusion
The typical repair costs for addressing an intermittent condition with the Intake Air Temperature (IAT) sensor on a 2010 Ford Fusion can range from $100 to $300, including parts and labor.
