P1114 2011 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 2011 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 2011 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 2011 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 2011 Ford Fusion Code
What does the OBDII code P1114 mean for a 2011 Ford Fusion?
P1114 indicates that the Intake Air Temperature (IAT) Sensor 2 circuit is reporting a voltage lower than the expected range, suggesting a potential issue with the sensor or wiring.
What are the symptoms of the P1114 code in a 2011 Ford Fusion?
Common symptoms include the check engine light turning on, reduced fuel efficiency, poor engine performance, and possible difficulty starting the vehicle.
What causes the P1114 code to appear in a 2011 Ford Fusion?
Possible causes include a faulty Intake Air Temperature Sensor 2, damaged or corroded wiring, a loose or disconnected sensor connector, or an issue with the powertrain control module (PCM).
Can I drive my 2011 Ford Fusion with the P1114 code?
Driving with this code is possible but not recommended, as it can lead to reduced engine performance and potential long-term damage if left unaddressed.
How do I diagnose the P1114 code in my 2011 Ford Fusion?
Start by inspecting the IAT Sensor 2 and its wiring for damage or corrosion. Use a multimeter to check sensor voltage and resistance, and verify that the sensor is receiving proper power and ground.
What tools are needed to fix the P1114 code in a 2011 Ford Fusion?
Basic tools include a multimeter, an OBDII scanner, and possibly replacement parts like a new IAT Sensor 2 or wiring repair supplies.
How can I fix the P1114 code in my 2011 Ford Fusion?
Repairs may include replacing the faulty IAT Sensor 2, repairing or replacing damaged wiring or connectors, and clearing the code with an OBDII scanner after repairs.
How much does it cost to fix the P1114 code in a 2011 Ford Fusion?
Repair costs can vary but typically range from $50 to $200, depending on whether the issue is with the sensor, wiring, or other components.
Can a dirty air filter cause the P1114 code in a 2011 Ford Fusion?
While unlikely, a clogged air filter can indirectly affect intake air temperature readings. It's a good idea to inspect the air filter during diagnosis.
Does the P1114 code require reprogramming the PCM?
In most cases, reprogramming the PCM is not necessary. However, if all other repairs fail and the PCM is determined to be faulty, reprogramming or replacement may be required.
