P0098 Mazda Code - Boost Air Temperature Sensor Circuit High
Quick Answer
The Intake Air Temperature (IAT) sensor contains a semiconductor device which changes the resistance based on the temperature (a thermistor). Common causes include Faulty Intake Air Temperature sensor, Intake Air Temperature sensor harness is open or shorted, Intake Air Temperature 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.
