P0098 2015 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 2015 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 2015 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 2015 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 2015 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 2015 Ford F150 Code
1. What does the OBDII code P0098 mean on a 2015 Ford F150?
P0098 indicates that the Intake Air Temperature (IAT) Sensor 2 Circuit on Bank 1 is reporting higher-than-expected voltage, which could signal a sensor or wiring issue.
2. What are the common symptoms of code P0098 in a 2015 Ford F150?
Symptoms may include poor engine performance, reduced fuel efficiency, difficulty starting, or an illuminated check engine light.
3. What causes the P0098 code on a 2015 Ford F150?
Common causes include a faulty Intake Air Temperature sensor, damaged or corroded wiring, a loose connector, or an issue with the engine control module (ECM).
4. Can I drive my 2015 Ford F150 with a P0098 code?
While the vehicle may still run, driving with a P0098 code can lead to reduced performance and potential long-term engine damage. It’s best to address the issue promptly.
5. How do I diagnose the P0098 code on my 2015 Ford F150?
Start by visually inspecting the IAT sensor and its wiring for damage or corrosion. Use a multimeter to test the sensor’s resistance and voltages, and check for continuity in the circuit.
6. How do I fix the P0098 code on a 2015 Ford F150?
Repairs may involve replacing the IAT sensor, repairing or replacing damaged wiring, cleaning corroded connectors, or updating/reprogramming the ECM.
7. Where is the Intake Air Temperature Sensor 2 located on a 2015 Ford F150?
The IAT Sensor 2 is usually integrated into the intake manifold or air intake duct, depending on the engine configuration.
8. How much does it cost to fix the P0098 code on a 2015 Ford F150?
The cost depends on the repair. Replacing the IAT sensor typically costs $50–$150 for parts, while labor can range from $50–$100.
9. Can a dirty air filter cause the P0098 code on a 2015 Ford F150?
A dirty air filter is unlikely to directly cause P0098, but it can affect airflow and the performance of the IAT sensor. Replacing the air filter is a good preventive step.
10. Will clearing the P0098 code solve the problem on my 2015 Ford F150?
Clearing the code may temporarily turn off the check engine light, but it won’t resolve the underlying issue. Proper diagnosis and repairs are necessary to prevent the code from returning.
