P0097 2019 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 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 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 2019 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 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 P0097 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 P0097 2019 Ford F150 Code
What does OBDII code P0097 mean on a 2019 Ford F150?
P0097 indicates that the Intake Air Temperature (IAT) Sensor 2 on Bank 1 is reporting a voltage that is lower than the expected range.
What are the common symptoms of code P0097 on a 2019 Ford F150?
Symptoms may include a check engine light, poor fuel efficiency, rough idling, reduced engine performance, or difficulty starting the engine.
What causes code P0097 to appear on a 2019 Ford F150?
Common causes include a faulty IAT sensor, damaged or corroded wiring, a loose or disconnected sensor connector, or issues with the engine control module (ECM).
How do you diagnose code P0097 on a 2019 Ford F150?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the IAT sensor and wiring, testing the sensor with a multimeter, and checking for continuity in the circuit.
Can a dirty air filter cause code P0097 on a 2019 Ford F150?
A dirty air filter is unlikely to directly cause P0097 but can contribute to related airflow issues. Inspect and replace the air filter if necessary.
How do you fix code P0097 on a 2019 Ford F150?
Repairs may include replacing the IAT sensor, repairing damaged wiring or connectors, cleaning the sensor, or, in rare cases, reprogramming or replacing the ECM.
Where is the Intake Air Temperature Sensor 2 located on a 2019 Ford F150?
IAT Sensor 2 is typically located in the intake manifold or near the air filter housing on Bank 1 of the engine.
Can you drive with code P0097 on a 2019 Ford F150?
While the vehicle may still be drivable, it is not recommended as it can lead to poor performance, increased emissions, and potential damage to other components if left unresolved.
How much does it cost to fix code P0097 on a 2019 Ford F150?
The cost can vary, but replacing the IAT sensor typically ranges from $100 to $300, including parts and labor. Additional repairs may increase the cost.
Can clearing the code with a scanner fix the issue?
Clearing the code may turn off the check engine light temporarily, but the underlying issue must be addressed to prevent the code from returning.
