P00AD Ford 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 Ford 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 Ford?
- 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 Ford?
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 Ford 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 Ford Code
1. What does the OBDII code P00AD mean on a Ford vehicle?
P00AD indicates that the Intake Air Temperature (IAT) Sensor 1 Circuit on Bank 2 is reading a voltage that is higher than the expected range, suggesting an issue with the sensor or its circuit.
2. What are the symptoms of the P00AD code on a Ford?
Common symptoms include poor engine performance, reduced fuel efficiency, difficulty starting the engine, and the Check Engine Light being illuminated.
3. What causes the P00AD code to appear on a Ford?
Possible causes include a faulty IAT sensor, damaged or corroded wiring or connectors in the circuit, a short to power, or a malfunctioning Engine Control Module (ECM).
4. How do I diagnose the P00AD code on my Ford?
Start by using a scan tool to confirm the code, inspect the IAT sensor and its wiring for damage, test the sensor's resistance, and check the circuit for shorts or open connections.
5. Can I drive my Ford with the P00AD code active?
While the vehicle may still be drivable, it’s not recommended as it could lead to poor engine performance and increased emissions, potentially causing further damage.
6. How is the P00AD code fixed on a Ford?
Repairs may include replacing the faulty IAT sensor, repairing damaged wiring or connectors, or reprogramming or replacing the ECM if necessary.
7. Where is the Intake Air Temperature Sensor 1 located on a Ford?
The IAT Sensor 1 is typically located near the air intake system, such as on the intake manifold or air filter housing, on Bank 2 (the side of the engine opposite Bank 1).
8. How much does it cost to fix the P00AD code on a Ford?
Repair costs vary but generally range between $50 to $200 for parts and labor, depending on whether the IAT sensor or wiring needs replacement.
9. Can a dirty air filter cause the P00AD code on a Ford?
A dirty air filter is unlikely to directly cause the P00AD code but could contribute to airflow issues, which might indirectly affect sensor readings.
10. How can I prevent the P00AD code from recurring on my Ford?
Regularly inspect and maintain the air intake system, ensure wiring and connectors are in good condition, and replace the IAT sensor as needed based on manufacturer recommendations.
