P0097 2020 Ford F150 Code - Intake Air Temperature Sensor 2 Circuit Low Input Bank 1
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 2 (IAT2) Sensor, Intake Air Temperature 2 Sensor harness is open or shorted, Intake Air Temperature 2 Sensor 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 P0097 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 IAT2 Sensor signal is less than the self-test minimum. The IAT2 sensor minimum is 0.2 volt.
What are the Possible Causes of the DTC P0097 2020 Ford F150?
- Faulty Intake Air Temperature 2 (IAT2) Sensor
- Intake Air Temperature 2 Sensor harness is open or shorted
- Intake Air Temperature 2 Sensor circuit poor electrical connection
How to Fix the DTC P0097 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 P0097 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 P0097 2020 Ford F150 Code
What does the OBDII code P0097 mean for a 2020 Ford F150?
P0097 indicates that the Intake Air Temperature (IAT) Sensor 2 is reporting a low input voltage on Bank 1, which can affect the engine's performance and fuel efficiency.
What are the common symptoms of code P0097?
Common symptoms include poor engine performance, reduced fuel efficiency, rough idling, and possible illumination of the check engine light.
What causes the P0097 code to trigger?
Causes can include a faulty IAT Sensor 2, damaged wiring or connectors, a short circuit in the sensor circuit, or issues with the engine control module (ECM).
How can I diagnose the P0097 code?
To diagnose, check the IAT sensor's wiring and connectors for damage, test the sensor with a multimeter, and inspect the engine for any vacuum leaks or related issues.
What are some repair tips for fixing code P0097?
Repair tips include replacing a faulty IAT sensor, repairing or replacing damaged wiring, and ensuring all electrical connections are secure and free of corrosion.
Can I drive my 2020 Ford F150 with the P0097 code?
While it may be drivable, it's not recommended to ignore the code, as it can lead to further engine performance issues and reduced fuel economy.
How much does it typically cost to repair code P0097?
Repair costs can vary widely depending on the underlying issue, but expect to pay between $100 to $300 for a sensor replacement or wiring repairs.
Will clearing the code P0097 reset the check engine light?
Yes, clearing the code will reset the check engine light, but if the underlying issue is not resolved, the code is likely to return.
What should I do if the P0097 code keeps coming back?
If the code persists after repairs, further diagnosis may be necessary to check for additional faults, such as other sensor issues or problems with the ECM.
Is there a difference between Intake Air Temperature Sensor 1 and Sensor 2?
Yes, Intake Air Temperature Sensor 1 is typically located in the air intake duct, while Sensor 2 is usually found in the manifold or a different location, providing additional data for engine management.
