P00AD 2019 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 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 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 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 P00AD 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 P00AD 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 P00AD 2019 Ford F150 Code
What does the OBDII code P00AD mean on a 2019 Ford F-150?
The P00AD code indicates that the Intake Air Temperature (IAT) Sensor 1 Circuit on Bank 2 is showing a high voltage signal, which suggests a potential issue with the sensor or its wiring.
What are the symptoms of code P00AD on a 2019 Ford F-150?
Common symptoms include a check engine light, poor fuel efficiency, reduced engine performance, rough idling, or inconsistent throttle response.
What causes the P00AD code on a 2019 Ford F-150?
Possible causes include a faulty IAT sensor, damaged or corroded wiring, a loose electrical connection, or an issue with the engine control module (ECM).
How do I fix the P00AD code on my 2019 Ford F-150?
Start by inspecting the IAT sensor and its wiring for damage or corrosion. Replace the sensor if necessary, and ensure all connections are secure. If the issue persists, further diagnosis may be needed.
Where is the Intake Air Temperature Sensor 1 located on a 2019 Ford F-150?
The IAT Sensor 1 for Bank 2 is typically located in the intake air tubing or near the air filter housing on the Bank 2 side of the engine.
Can I drive my 2019 Ford F-150 with a P00AD code?
While it may be possible to drive with this code, it is not recommended as it could lead to poor performance, reduced fuel efficiency, and potential engine damage over time.
How much does it cost to fix the P00AD code on a 2019 Ford F-150?
The repair cost depends on the issue. Replacing an IAT sensor typically costs $50–$150 for parts and labor, but wiring repairs or ECM diagnosis may increase the expense.
Can a dirty air filter cause the P00AD code on a 2019 Ford F-150?
A dirty air filter is unlikely to cause this specific code, but it can indirectly affect other engine performance metrics. It’s still a good idea to check and replace the air filter if needed.
How can I diagnose the P00AD code on my 2019 Ford F-150?
Use an OBDII scanner to confirm the code and check for related codes. Inspect the IAT sensor, wiring, and connectors for visible damage or corrosion. Test the sensor's voltage and resistance with a multimeter.
Does the P00AD code indicate a problem with Bank 1 or Bank 2?
The P00AD code specifically refers to Bank 2, which is the side of the engine opposite Bank 1. This is important for locating and diagnosing the issue.
