The 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 to optimize performance and fuel efficiency.
Common Causes of P0112 2011 Ford Fusion
- Faulty IAT sensor
- Damaged or corroded wiring in the sensor circuit
- Loose or poor connection at the sensor
- Faulty ECM
- Intake air leaks near the sensor
Symptoms of P0112 2011 Ford Fusion
- Decreased fuel efficiency
- Rough idling or stalling
- Hesitation or lack of power during acceleration
- Engine running too rich or too lean
- Check Engine Light illuminated
How to Fix P0112 2011 Ford Fusion
- Begin by locating the IAT sensor in the intake air duct or near the air filter housing.
- Inspect the sensor and its wiring for any visible damage, corrosion, or loose connections.
- Test the IAT sensor using a multimeter to check for proper voltage readings.
- If the sensor is faulty, replace it with a new one following manufacturer guidelines.
- Clear the diagnostic trouble codes with a scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0112 2011 Ford Fusion
