P0098 2018 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 2018 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 2018 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 2018 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 2018 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 2018 Ford F150 Code
1. What does the OBDII code P0098 mean on a 2018 Ford F150?
P0098 indicates that the Intake Air Temperature (IAT) Sensor 2 on Bank 1 is detecting a voltage signal higher than the expected range.
2. What are the common symptoms of code P0098 on a 2018 Ford F150?
Symptoms may include poor engine performance, decreased fuel efficiency, rough idling, and possible illumination of the check engine light.
3. What causes the P0098 code to trigger on a 2018 Ford F150?
Common causes include a faulty IAT sensor, damaged or corroded wiring, loose or disconnected connectors, or an issue with the vehicle's PCM.
4. How do I diagnose the P0098 code on my 2018 Ford F150?
Start by inspecting the IAT sensor and its wiring for damage or corrosion. Use a multimeter to test the sensor’s resistance and check the PCM for proper voltage signals.
5. Can I drive my 2018 Ford F150 with the P0098 code?
While the vehicle may still be drivable, it’s not recommended as it can lead to decreased performance and potential damage to engine components.
6. How do I fix the P0098 code on a 2018 Ford F150?
Repairs may involve replacing the IAT sensor, repairing or replacing damaged wiring or connectors, or reprogramming/updating the PCM if necessary.
7. Where is the Intake Air Temperature Sensor 2 located on a 2018 Ford F150?
The IAT Sensor 2 is typically located near the air intake system, downstream of the air filter or integrated into the mass airflow (MAF) sensor.
8. How much does it cost to repair the P0098 code on a 2018 Ford F150?
Repair costs may range from $75 to $200 depending on whether the issue is with the sensor, wiring, or PCM. Labor costs will vary by location.
9. Can a dirty air filter cause the P0098 code on a 2018 Ford F150?
A dirty air filter is unlikely to directly cause the P0098 code but may contribute to performance issues. Always inspect and replace the air filter if needed.
10. Will clearing the P0098 code fix the issue on my 2018 Ford F150?
Clearing the code will reset the check engine light temporarily but won’t fix the underlying issue. Proper diagnosis and repair are necessary to prevent the code from returning.
