P00AB 2015 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 2015 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 2015 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 2015 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 2015 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 2015 Ford F150 Code
1. What does OBDII code P00AB indicate on a 2015 Ford F150?
- Code P00AB indicates an issue with the Intake Air Temperature Sensor 1 Circuit Range/Performance for Bank 2, suggesting that the sensor is not operating within its expected parameters.
2. What symptoms might I notice if my vehicle has the P00AB code?
- Symptoms can include a check engine light, poor engine performance, increased fuel consumption, and potential issues with engine starting or rough idling.
3. What can cause the P00AB code to appear on a 2015 Ford F150?
- Potential causes include a faulty intake air temperature sensor, wiring issues like shorts or disconnections in the sensor circuit, or problems with the engine control module.
4. How can I fix the P00AB code in a 2015 Ford F150?
- To fix this code, inspect and replace the intake air temperature sensor if necessary, repair any damaged wires or connectors in the sensor circuit, or consider replacing the engine control module if it is faulty.
5. Is it safe to drive my 2015 Ford F150 with the P00AB code?
- While you can technically still drive, it's advisable to address the issue promptly as it can lead to reduced performance and potential long-term damage to the engine.
6. How do I check the intake air temperature sensor to confirm it's causing the P00AB code?
- Use a multimeter to check the sensor’s resistance and compare it to manufacturer specifications. A sensor outside of these specifications likely needs replacement.
7. What tools are needed to diagnose the P00AB code on a 2015 Ford F150?
- A scan tool or code reader, a multimeter, and basic hand tools to access and test the sensor and wiring are essential for diagnosing this code.
8. Can a dirty air filter cause the P00AB code in a 2015 Ford F150?
- While a dirty air filter itself might not directly trigger this code, it can affect overall air intake and engine performance, potentially exacerbating issues related to the air temperature sensor.
9. What is the role of the intake air temperature sensor in a 2015 Ford F150?
- The intake air temperature sensor measures the temperature of the air entering the engine to help the engine control unit adjust the fuel mixture and ignition timing for optimal performance.
10. How often should the intake air temperature sensor be replaced in a 2015 Ford F150?
- There is no specific replacement interval for the intake air temperature sensor. It should be replaced as needed based on diagnostic testing and symptom evaluation.
