Intake Air Temperature Sensor 2 Circuit High Bank 1
This code means that the computer in your car thinks the sensor that measures the temperature of the air going into the engine is reading too high. It's like the sensor is saying the air is much hotter than it really is.
The P0098 code is triggered when the powertrain control module (PCM) detects a voltage signal from the Intake Air Temperature (IAT) Sensor 2 that is higher than the expected range.
The Intake Air Temperature Sensor 2 is responsible for measuring the temperature of the air entering the engine. This information is used by the PCM to adjust fuel delivery and ignition timing for optimal performance. A 'circuit high' condition indicates that the sensor is sending a higher voltage signal than normal, which could be due to a malfunctioning sensor, wiring issues, or a problem with the PCM.
• Use an OBD-II scanner to confirm the P0098 code.
• Inspect the IAT sensor and its wiring for damage or loose connections.
• Test the IAT sensor's resistance and compare it to specifications.
• Replace the faulty IAT sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

• Regularly inspect sensor wiring and connections.
• Replace air filters as needed to prevent sensor contamination.
• Perform regular vehicle maintenance.
Sensor Issue
• Do not ignore the Check Engine Light.
• Seek professional diagnosis if unsure.
• Avoid driving the vehicle hard until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on sensors.
The P0098 code has been associated with issues in vehicles that have had sensor or wiring problems, often due to environmental exposure or age.
Moderate – While not critical, it should be addressed to prevent potential engine performance issues.
Driving with a faulty sensor can lead to increased emissions and may not pass emissions testing.
• Engine at operating temperature
• Vehicle in park or neutral
The Intake Air Temperature Sensor 2 is typically located in the air intake duct or manifold.
Q: Can I drive with a P0098 code?
A: It's possible to drive, but it's not recommended as it can affect engine performance and fuel economy.
Q: How do I reset the P0098 code?
A: After repairs, use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes.
