P1114 2007 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 2007 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 2007 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 2007 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 2007 Ford Fusion Code
What does the OBDII code P1114 mean for a 2007 Ford Fusion?
P1114 indicates a problem with the Intake Air Temperature Sensor 2 Circuit, specifically that the sensor is reporting a low voltage reading.
What are the common symptoms of code P1114 on a 2007 Ford Fusion?
Symptoms may include poor engine performance, reduced fuel efficiency, difficulty starting, and the check engine light being illuminated.
What causes the P1114 code to appear in a 2007 Ford Fusion?
Common causes include a faulty intake air temperature (IAT) sensor, damaged wiring, loose electrical connections, or corrosion in the circuit.
How does the intake air temperature sensor affect engine performance?
The IAT sensor helps the engine control module (ECM) adjust air-fuel mixture based on air temperature, ensuring optimal performance and efficiency. A malfunction can disrupt this balance.
Can I drive my 2007 Ford Fusion with the P1114 code?
While the car may still be drivable, ignoring the issue can lead to reduced engine performance and potential long-term damage. It's best to address the problem promptly.
How do I diagnose the cause of code P1114 in a 2007 Ford Fusion?
Use a multimeter to check the IAT sensor’s resistance and inspect the wiring and connectors for damage or corrosion. You may need an OBDII scanner to confirm the code.
How do I fix code P1114 on a 2007 Ford Fusion?
Repairs may involve replacing the intake air temperature sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or ensuring proper electrical connections.
What tools are needed to repair the P1114 code on a 2007 Ford Fusion?
You may need an OBDII scanner, multimeter, basic hand tools, and possibly replacement parts like a new IAT sensor or wiring.
Can a dirty air filter cause the P1114 code?
While unlikely, a severely clogged air filter can affect airflow and sensor readings. It’s a good idea to check and replace the air filter if needed.
How much does it cost to fix the P1114 code on a 2007 Ford Fusion?
The cost varies depending on the cause, but replacing the IAT sensor typically costs $50-$150 for parts and labor, while wiring repairs may be slightly higher.
