P1114 2006 Ford Fusion Code - Intake Air Temperature Sensor 2 Circuit Low
Quick Answer
The IAT sensor is a thermistor device in which resistance changes with temperature. Common causes include Faulty Intake Air Temperature Sensor 2, Intake Air Temperature Sensor 2 harness is open or shorted, Intake Air Temperature Sensor 2 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 P1114 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 P1114 2006 Ford Fusion?
- Faulty Intake Air Temperature Sensor 2
- Intake Air Temperature Sensor 2 harness is open or shorted
- Intake Air Temperature Sensor 2 circuit poor electrical connection
- Damaged Powertrain Control Module (PCM)
How to Fix the DTC P1114 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 P1114 2006 Ford Fusion Code
What does the OBDII code P1114 mean on a 2006 Ford Fusion?
P1114 indicates an issue with the Intake Air Temperature (IAT) Sensor 2 Circuit, specifically that the sensor is detecting a voltage lower than expected.
What are the common symptoms of code P1114 in a 2006 Ford Fusion?
Symptoms may include poor fuel efficiency, rough idling, reduced engine performance, and the check engine light being illuminated.
What causes the P1114 code in a 2006 Ford Fusion?
Possible causes include a faulty IAT sensor 2, damaged wiring or connectors, a short circuit, or an issue with the engine control module (ECM).
How does the Intake Air Temperature Sensor 2 work?
The IAT sensor 2 measures the temperature of the air entering the engine and sends this information to the ECM to adjust fuel delivery and ignition timing.
Can I drive my 2006 Ford Fusion with a P1114 code?
Driving with a P1114 code is not recommended, as it may lead to reduced fuel efficiency, performance issues, and potential engine damage over time.
How do I diagnose the P1114 code on a 2006 Ford Fusion?
Diagnosis involves checking the IAT sensor 2 for proper operation, inspecting wiring and connectors for damage, and using a multimeter to measure voltage and resistance in the circuit.
How do I fix the P1114 code on a 2006 Ford Fusion?
Repairs may include replacing the faulty IAT sensor 2, repairing damaged wiring or connectors, or addressing any short circuits in the sensor's circuit.
Where is the IAT sensor 2 located on a 2006 Ford Fusion?
IAT sensor 2 is typically located in the air intake system, often near the throttle body or air filter housing.
How much does it cost to fix the P1114 code on a 2006 Ford Fusion?
Repair costs can range from $50 to $200, depending on whether the sensor, wiring, or other components need to be replaced.
Can a dirty air filter cause the P1114 code?
While unlikely, a severely dirty air filter can restrict airflow and potentially affect IAT sensor readings, so it’s worth checking as part of the diagnosis.
