Code P0098 Ford Description

The P0098 Ford diagnostic trouble code indicates a high voltage condition in the Intake Air Temperature Sensor (IAT) 2 circuit in Bank 1. The IAT sensor is responsible for monitoring the temperature of the air entering the engine, which is crucial for determining the air-fuel mixture needed for combustion. A high voltage reading suggests that the sensor is reporting a temperature higher than expected, which can lead to incorrect fuel delivery and potentially cause drivability issues.
