P1112 2006 Ford Fusion Code - Intake Air Temperature Sensor Intermittent Condition
Quick Answer
The IAT sensor is a thermistor device in which resistance changes with temperature. Common causes include Faulty Intake Air Temperature Sensor, Intake Air Temperature Sensor harness is open or shorted, Intake Air Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1112 2006 Ford Fusion Description
Thermistor-type sensors are considered passive sensors. A passive sensor is connected to a voltage divider network so that varying the resistance of the passive sensor causes a variation in total current flow. Voltage that is dropped across a fixed resistor in a series with the sensor resistor determines the voltage signal at the PCM. This voltage signal is equal to the reference voltage minus the voltage drop across the fixed resistor.
The IAT sensor provides air temperature information to the PCM. The PCM uses the air temperature information as a correction factor in the calculation of fuel, spark, and air flow.
The IAT sensor provides a quicker temperature change response time than the ECT or CHT sensor.
Currently there are 2 types of IAT sensors used, a stand alone, non-integrated type and an integrated type. Both types function the same, however the integrated type is incorporated into the mass air flow (MAF) sensor instead of being a stand-alone sensor.
What are the Possible Causes of the DTC P1112 2006 Ford Fusion?
- Faulty Intake Air Temperature Sensor
- Intake Air Temperature Sensor harness is open or shorted
- Intake Air Temperature Sensor circuit poor electrical connection
- Damaged Powertrain Control Module (PCM)
How to Fix the DTC P1112 2006 Ford Fusion?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.

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.
