P00AB 2019 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 2019 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 2019 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 2019 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 2019 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 2019 Ford F150 Code
1. What does the OBDII code P00AB mean on a 2019 Ford F-150?
The P00AB code indicates an issue with the Intake Air Temperature Sensor 1 Circuit Range/Performance on Bank 2, meaning the sensor is not functioning within the expected parameters.
2. What are common symptoms of the P00AB code in a 2019 Ford F-150?
Symptoms can include poor engine performance, rough idling, reduced fuel efficiency, or the Check Engine Light being illuminated.
3. What causes the P00AB code to appear on a 2019 Ford F-150?
Common causes include a faulty intake air temperature sensor, wiring issues, poor electrical connections, or a malfunctioning powertrain control module (PCM).
4. Where is Intake Air Temperature Sensor 1 located on a 2019 Ford F-150?
Intake Air Temperature Sensor 1 is typically integrated into the mass airflow (MAF) sensor on the intake tubing, and Bank 2 refers to the side of the engine opposite Cylinder 1.
5. Can I drive my 2019 Ford F-150 with a P00AB code?
While the truck may still be drivable, it’s not recommended to ignore the code, as it can lead to poor performance and potential long-term engine damage.
6. How do I fix the P00AB code on a 2019 Ford F-150?
Fixes may involve replacing the intake air temperature sensor, repairing or replacing damaged wiring, or cleaning the sensor if it is dirty.
7. How much does it cost to repair a P00AB code on a 2019 Ford F-150?
The cost varies, but replacing the intake air temperature sensor typically ranges from $50 to $200, depending on parts and labor.
8. Can a dirty air filter cause the P00AB code on a 2019 Ford F-150?
A clogged or dirty air filter can indirectly affect air intake readings, but it is not a direct cause of the P00AB code.
9. How do I diagnose the P00AB code on my 2019 Ford F-150?
Use an OBDII scanner to confirm the code, inspect the intake air temperature sensor and wiring for damage, and check for proper connections or debris near the sensor.
10. Will resetting the Check Engine Light fix the P00AB code on a 2019 Ford F-150?
Resetting the light may temporarily clear the code, but it will reappear if the underlying issue is not resolved.
