P00AD 2020 Ford F150 Code - Intake Air Temperature Sensor 1 Circuit High 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 P00AD 2020 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 greater than the self-test maximum.
What are the Possible Causes of the DTC P00AD 2020 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 P00AD 2020 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 P00AD 2020 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 P00AD 2020 Ford F150 Code
1. What does the OBDII code P00AD indicate on a 2020 Ford F150?
The P00AD code indicates that the Intake Air Temperature Sensor 1 Circuit High Bank 2 has detected a voltage or resistance input that is higher than the expected parameters, suggesting a potential issue with the sensor or its circuit.
2. What are common symptoms of the P00AD code in a 2020 Ford F150?
Common symptoms include a check engine light, reduced engine performance, poor fuel economy, and possible stalling or hesitation during acceleration.
3. What could cause the P00AD code to appear in a 2020 Ford F150?
Possible 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 (ECM).
4. How can I diagnose the cause of a P00AD code in a 2020 Ford F150?
Diagnosis should start with using an OBDII scanner to confirm the code, followed by a visual inspection of the sensor and its wiring. Further testing with a multimeter can help determine if the sensor or the wiring is at fault.
5. What steps should be taken to fix the P00AD code in a 2020 Ford F150?
Repair steps may include replacing the intake air temperature sensor, repairing or replacing damaged wiring or connectors, and in rare cases, replacing or reprogramming the engine control module.
6. Is it safe to drive a 2020 Ford F150 with a P00AD code?
While you can drive the vehicle, it is not recommended as the issue can affect the engine's performance and fuel efficiency. Continued driving could potentially lead to further complications.
7. How urgent is it to address a P00AD code on a 2020 Ford F150?
It is moderately urgent to address this code because the engine may experience performance issues. It's advisable to fix the problem soon to avoid potential engine damage or other related issues.
8. Can a P00AD code clear itself if the issue resolves on a 2020 Ford F150?
While some codes may clear if the issue is intermittent or resolves, for a P00AD code, it is unlikely to clear without manual resetting after the underlying issue has been fixed. Regular diagnostic checks are recommended to ensure the problem is fully resolved.
