P1114 2000 Ford F150 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 2000 Ford F150 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 2000 Ford F150?
- 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 2000 Ford F150?
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 2000 Ford F150 Code
What does the OBDII code P1114 mean on a 2000 Ford F150?
The P1114 code indicates a problem with the Intake Air Temperature (IAT) Sensor 2 Circuit, specifically that the sensor signal is reading lower than expected.
What are the symptoms of code P1114 on a 2000 Ford F150?
Common symptoms include poor fuel efficiency, rough idling, reduced engine performance, and possibly an illuminated Check Engine Light.
What causes the P1114 code to appear on a 2000 Ford F150?
Possible causes include a faulty IAT sensor, damaged or corroded wiring, loose connections, or issues with the engine control module (ECM).
How does the Intake Air Temperature Sensor affect the engine?
The IAT sensor measures the temperature of incoming air, and the ECM uses this data to adjust the air-fuel mixture for optimal performance and efficiency.
Can I drive my 2000 Ford F150 with the P1114 code?
While the vehicle may still be operable, driving with the P1114 code could lead to reduced performance and fuel economy. It’s best to address the issue promptly.
How do I diagnose the P1114 code on a 2000 Ford F150?
Start by inspecting the IAT sensor and its wiring for damage or corrosion. Use a multimeter to test the sensor’s resistance and verify proper voltage at the connector.
How do I fix the P1114 code on a 2000 Ford F150?
Repairs may include replacing the IAT sensor, repairing damaged wiring or connectors, or cleaning corrosion from electrical contacts.
Where is the Intake Air Temperature Sensor 2 located on a 2000 Ford F150?
The IAT Sensor 2 is typically located near or integrated with the air intake system, often in the air filter housing or intake manifold.
How much does it cost to repair the P1114 code on a 2000 Ford F150?
Repair costs vary but typically range from $50 to $200, depending on whether the sensor or wiring needs replacement and if labor costs are involved.
Can a dirty air filter cause the P1114 code on a 2000 Ford F150?
While a dirty air filter is unlikely to directly cause the P1114 code, it can restrict airflow and potentially affect the IAT sensor’s readings.
