P1115 2001 Ford F150 Code - Intake Air Temperature Sensor 2 Circuit High
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 P1115 2001 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 P1115 2001 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 P1115 2001 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.
