P00AB 2016 Ford F150 Code - Intake Air Temperature Sensor 1 Circuit Range/Performance 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 P00AB 2016 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 DTC P0111 is not present and the Intake Air Temperature Bank 2, Sensor 1 (IAT21) value does not correlate with the Intake Air Temperature Bank 1, Sensor 1 (IAT11) value at ignition ON after a calibrated soak period (typically 6 to 8 hours). This DTC also sets if the IAT21 sensor value exceeds the maximum calibrated temperature threshold while driving at a low load and a speed greater than 56 kMH (35 MPH).
What are the Possible Causes of the DTC P00AB 2016 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 P00AB 2016 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 P00AB 2016 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.

Frequently Asked Questions about P00AB 2016 Ford F150 Code
What does the OBDII code P00AB mean for a 2016 Ford F150?
The P00AB code indicates an issue with the Intake Air Temperature Sensor 1 Circuit Range/Performance on Bank 2, meaning the sensor is detecting values outside the expected range.
What are the symptoms of a P00AB code on a 2016 Ford F150?
Common symptoms include reduced engine performance, hesitation during acceleration, poor fuel efficiency, and potential illumination of the check engine light.
What causes the P00AB code to appear?
Possible causes include a faulty intake air temperature sensor, damaged wiring or connectors, a dirty or malfunctioning air filter, or issues with the powertrain control module (PCM).
How can I diagnose the P00AB code on my 2016 Ford F150?
Start by inspecting the intake air temperature sensor and its wiring for damage. Use an OBDII scanner to check live data and compare the readings of Bank 2 with Bank 1 to identify discrepancies.
Can a dirty air filter cause the P00AB code?
Yes, a clogged or dirty air filter can restrict airflow and cause inaccurate readings from the intake air temperature sensor, triggering the code.
Is it safe to drive with the P00AB code on my 2016 Ford F150?
While the vehicle may still be drivable, driving with this code can lead to decreased performance and fuel economy. It’s best to address the issue promptly to avoid further damage.
How do I fix the P00AB code on a 2016 Ford F150?
Repairs may include cleaning or replacing the intake air temperature sensor, repairing damaged wiring, replacing the air filter, or reprogramming the PCM if necessary.
Where is the intake air temperature sensor located on a 2016 Ford F150?
The intake air temperature sensor is typically located near the air intake duct or integrated into the mass airflow sensor, depending on the engine configuration.
Can a P00AB code cause my 2016 Ford F150 to fail an emissions test?
Yes, this code can cause your vehicle to fail an emissions test because it may affect the air-fuel mixture, leading to increased emissions.
Do I need professional help to fix the P00AB code?
While some issues like replacing the air filter or inspecting wiring can be done at home, diagnosing and repairing sensor or PCM-related problems may require professional assistance.
