Blown fuse supplying the heater circuit
The fuse feeding sensor heaters, which are often grouped on one circuit. So a single fuse takes out several sensors at once, and a set of heater codes arriving together is one fuse rather than several failed sensors. A fuse that blows again immediately is reporting a short.
Typically an easy fix. Often worth checking before paying anyone to look.

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.
