P0098 2019 Ford F150 Code - Intake Air Temperature Sensor 2 Circuit High Voltage 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 P0098 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 greater than the self-test maximum. The IAT2 sensor maximum is 4.6 volts.
What are the Possible Causes of the DTC P0098 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 P0098 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 P0098 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 P0098 2019 Ford F150 Code
What does the OBDII code P0098 indicate on a 2019 Ford F150?
P0098 indicates that the Engine Control Module (ECM) has detected a high voltage input from the Intake Air Temperature Sensor 2 in Bank 1, which suggests that the sensor might be malfunctioning or there is an issue in the sensor circuit.
What are common symptoms of code P0098 in a 2019 Ford F150?
Symptoms can include a check engine light, reduced engine performance, poor fuel economy, and potential issues with the engine starting or running smoothly.
What causes the P0098 code to appear on a 2019 Ford F150?
Common causes include a faulty intake air temperature sensor, wiring issues like shorts or opens in the sensor circuit, or problems with the ECM itself.
How can I diagnose the P0098 code on my 2019 Ford F150?
Diagnosis should start with scanning and recording the freeze frame data. Then, visually inspect the sensor and circuit for any obvious damage. Use a multimeter to check for proper voltage and ground at the sensor, and consider checking the sensor's resistance to ensure it matches manufacturer specifications.
What steps should be taken to fix an intake air temperature sensor issue indicated by code P0098 in a 2019 Ford F150?
Repair might involve replacing the intake air temperature sensor, repairing or replacing damaged wires in the sensor circuit, or in rare cases, replacing or reprogramming the ECM.
Can I drive my 2019 Ford F150 with the P0098 code without fixing it immediately?
While you may be able to drive with this code active, it's not recommended as it can lead to poor engine performance, increased fuel consumption, and potential long-term damage to the engine.
Is the P0098 code serious for the 2019 Ford F150?
Yes, it is fairly serious because it affects the engine's ability to accurately read air temperature, which can alter fuel mixture and engine performance, potentially leading to further engine damage if not addressed.
What tools are needed to resolve a P0098 code on a 2019 Ford F150?
Tools needed may include a digital multimeter, a scan tool, basic hand tools for accessing the sensor, and possibly a wiring diagram for tracing the circuit issues effectively.
How often does the P0098 code occur in the 2019 Ford F150?
The frequency of this code can vary based on maintenance habits, environmental conditions, and the quality of the components used in the intake air temperature system. Proper maintenance and use of quality parts can help reduce the occurrence of this issue.
