Code P0098 2018 Chevrolet Silverado Description
The P0098 diagnostic trouble code (DTC) for a 2018 Chevrolet Silverado refers to an issue with the Intake Air Temperature Sensor 2 Circuit registering a high voltage. The Intake Air Temperature Sensor (IAT) is a crucial component of the engine's air intake system, responsible for measuring the temperature of the incoming air. This information is used by the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion efficiency. When the ECM detects a high voltage signal from the IAT Sensor 2 Circuit, it triggers the P0098 code.
Common Causes of P0098 2018 Chevrolet Silverado
- Faulty Intake Air Temperature Sensor
- Wiring or connector issues in the IAT Sensor circuit
- ECM software or hardware malfunction
- Intake air leaks near the sensor
- Extreme temperature conditions affecting sensor readings
Symptoms of P0098 2018 Chevrolet Silverado
- Check Engine Light illuminated on the dashboard
- Reduced fuel efficiency
- Engine running rough or misfiring
- Engine stalling or hesitation during acceleration
- Increased emissions output
How to Fix P0098 2018 Chevrolet Silverado
- Begin by diagnosing the issue using a scan tool to confirm the P0098 code and check the IAT Sensor 2 Circuit for high voltage.
- Inspect the wiring and connectors associated with the IAT Sensor for any damage or corrosion. Repair or replace as necessary.
- Test the Intake Air Temperature Sensor for proper operation using a multimeter to check resistance and voltage readings.
- If the sensor is faulty, replace it with a new one following manufacturer's guidelines.
- Clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0098 2018 Chevrolet Silverado
