P0098: Intake Air Temperature Sensor 2 Circuit High Bank 1
What to do
Usually driveable with reduced performance. Recent work on the intake or intercooler is worth mentioning.
What this code means
Voltage on the second intake air temperature circuit is above the expected range, usually an open circuit or a short to supply. An unplugged sensor produces exactly this code, so confirm the connector is seated before any testing begins — it is a common finding after intercooler or charge pipe work.
Likely causes
Start here
- Open circuit in sensor wiring · moderate
- Corroded or loose connector · easy
- Sensor left disconnected after previous work · easy
- Faulty intake air temperature sensor · easy
Less common
- Wiring shorted to voltage · moderate

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
