P0098

DTC P0098, sometimes indicated as P009800 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing intake air temperature sensor 2 circuit high bank 1.

This DTC code is caused by a high input voltage reading from the intake air temperature (IAT) sensor 2. This high voltage can be caused by a short or open circuit in the wiring, a bad sensor, or a problem in the engine control module (ECM).
The first step in troubleshooting this code is to check the wiring and connectors for damage or corrosion. If the wiring or connectors are OK, then the next step is to test the IAT sensor 2 for continuity and resistance. If the sensor is bad, then it will need to be replaced. If the sensor is OK, then the next step is to test the ECM for faults.
