P00AC 2017 Ford F150 Code - Intake Air Temperature Sensor 1 Circuit Low Bank 2
Quick Answer
The Intake Air Temperature (IAT) Sensor is a thermistor device in which resistance changes with temperature. Common causes include Faulty Intake Air Temperature Bank 2 Sensor 1 (IAT21), Intake Air Temperature Bank 2 Sensor 1 harness is open or shorted, Intake Air Temperature Bank 2 Sensor 1 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 P00AC 2017 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. The 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 airflow.
The IAT sensor provides a quicker temperature change response time than the Engine Coolant Temperature (ECT) or Cylinder Head Temperature (CHT) sensor.
Currently, there are 2 types of IAT sensors used, a stand-alone and an integrated type. Both types function the same, however, the integrated type is incorporated into the Mass Air Flow (MAF) Sensor, the Manifold Absolute Pressure and Temperature (MAPT) Sensor, or the Turbocharger Intake Pressure and Temperature (TCIPT) Sensor instead of being a stand-alone sensor.
The Intake Air Temperature 2 (IAT2) Sensor is typically located near the intake manifold and is used to measure the intake manifold temperature. The PCM uses this information to determine the air charge and provide input for various engine control functions. The IAT2 sensor may be integrated with the Manifold Absolute Pressure (MAP) Sensor.
This Diagnostic Trouble Code (DTC) is set when the Intake Air Temperature Bank 2, Sensor 1 (IAT21) sensor signal is less than the self-test minimum.
What are the Possible Causes of the DTC P00AC 2017 Ford F150?
- Faulty Intake Air Temperature Bank 2 Sensor 1 (IAT21)
- Intake Air Temperature Bank 2 Sensor 1 harness is open or shorted
- Intake Air Temperature Bank 2 Sensor 1 circuit poor electrical connection
How to Fix the DTC P00AC 2017 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.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P00AC 2017 Ford F150 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.
