P0111: Intake Air Temperature Sensor 1 Circuit Range/Performance Bank 1
What to do
Usually driveable with slightly worse economy. Fix at the next convenient service.
What this code means
The intake air temperature reading is plausible in isolation but disagrees with the other temperature sensors. The module makes this comparison at key-on after a long soak, when coolant, intake and ambient temperatures should all read close together. A sensor that fails that check is drifting, even if it responds normally once the engine warms.
Likely causes

Less common
- Sensor heat soak from poor mounting or airflow · moderate
- Corroded or loose connector · easy

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.

What makes one worth reading:
- 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.
