Code P1112 2006 Ford Fusion Description
The P1112 diagnostic trouble code (DTC) for a 2006 Ford Fusion specifically refers to an Intake Air Temperature Sensor Intermittent Condition. The Intake Air Temperature (IAT) sensor is a crucial component of the vehicle's engine management system, as it measures the temperature of the incoming air to the engine. This information is used by the engine control module (ECM) to adjust fuel delivery and ignition timing for optimal performance and efficiency.
Common Causes of P1112 2006 Ford Fusion
- Faulty IAT Sensor: The sensor itself may be malfunctioning, providing inconsistent temperature readings to the ECM.
- Wiring or Connector Issues: Damaged or corroded wiring or connectors can disrupt the signal between the IAT sensor and the ECM.
- ECM Malfunction: A problem with the engine control module can also lead to an intermittent IAT sensor condition.
- Environmental Factors: Extreme temperatures or exposure to moisture can affect the sensor's performance.
- Poor Maintenance: Lack of regular maintenance or neglecting to address other engine issues can contribute to sensor malfunctions.
Symptoms of P1112 2006 Ford Fusion
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the vehicle's dashboard.
- Reduced Engine Performance: The engine may experience a decrease in power and responsiveness, especially during acceleration.
- Poor Fuel Efficiency: The vehicle may consume more fuel than usual due to incorrect fuel adjustments based on inaccurate temperature readings.
- Rough Idle: The engine may idle erratically or inconsistently, causing vibrations or shaking in the vehicle.
- Emissions Issues: The vehicle may fail emissions tests due to the incorrect fuel and ignition adjustments caused by the faulty IAT sensor.
How to Fix P1112 2006 Ford Fusion
- Diagnostic Testing: Use a scan tool to retrieve the DTC and perform further testing to confirm the intermittent IAT sensor condition.
- Inspect Wiring and Connectors: Check the wiring and connectors for any damage, corrosion, or loose connections. Repair or replace as needed.
- Replace IAT Sensor: If the sensor is faulty, replace it with a new, OEM-quality sensor to ensure accurate temperature readings.
- Clear DTCs: Clear the DTC from the ECM's memory using the scan tool after completing the repair.
- Test Drive: Take the vehicle for a test drive to ensure the issue has been resolved and that the engine performance and fuel efficiency have returned to normal.
Cost to Fix P1112 2006 Ford Fusion
The typical repair costs for addressing an intermittent IAT sensor condition can vary depending on the specific cause of the issue and the labor rates in your area. In general, the cost of a new IAT sensor can range from $20 to $100, depending on the brand and quality. Labor costs for diagnosis and repair can range from $100 to $300, depending on the shop's hourly rates and the complexity of the repair. Overall, you can expect to pay anywhere from $120 to $400 for parts and labor to resolve this issue. Keep in mind that these are rough estimates, and actual costs may vary based on your location and the specific circumstances of your vehicle. It's recommended to consult with a qualified mechanic or auto repair shop for a more accurate cost estimate.

Frequently Asked Questions about P1112 2006 Ford Fusion Code
What does the OBDII code P1112 mean on a 2006 Ford Fusion?
P1112 indicates an intermittent condition with the Intake Air Temperature (IAT) sensor, meaning the sensor's signal is inconsistent or out of range.
What are the symptoms of a P1112 code on a 2006 Ford Fusion?
Common symptoms include rough idling, poor fuel economy, reduced engine performance, and possibly the Check Engine Light being illuminated.
What causes the P1112 code to appear on a 2006 Ford Fusion?
The code can be caused by a faulty IAT sensor, damaged wiring or connectors, a loose electrical connection, or a malfunctioning Powertrain Control Module (PCM).
Can I drive my 2006 Ford Fusion with a P1112 code?
While the car may still be drivable, continuing to drive with this code can lead to reduced performance and potential long-term engine damage if the issue is not addressed.
How do you diagnose a P1112 code on a 2006 Ford Fusion?
Diagnosing involves visually inspecting the IAT sensor, wiring, and connectors for damage, testing the sensor's resistance with a multimeter, and checking for loose or corroded connections.
How do you fix a P1112 code on a 2006 Ford Fusion?
Repairs may include replacing the faulty IAT sensor, repairing or replacing damaged wiring or connectors, cleaning electrical connections, or reprogramming the PCM if necessary.
Where is the Intake Air Temperature (IAT) sensor located on a 2006 Ford Fusion?
The IAT sensor is typically located near the intake manifold or within the air intake system, often integrated into the Mass Airflow (MAF) sensor.
How much does it cost to fix a P1112 code on a 2006 Ford Fusion?
Costs can range from $50 to $200 for parts and labor, depending on whether the issue is with the IAT sensor, wiring, or PCM.
Can a dirty air filter cause the P1112 code on a 2006 Ford Fusion?
While a dirty air filter is unlikely to directly cause this code, it can contribute to airflow issues that may indirectly affect IAT sensor readings.
Do I need to clear the P1112 code after repairs on a 2006 Ford Fusion?
Yes, after completing repairs, clearing the code with an OBDII scanner is recommended to verify that the issue has been resolved.
