Cause
Water ingress into connector
Water sitting in a connector body, bridging terminals and corroding them. The fault follows weather rather than driving, which is the strongest clue available and one only the owner can report.
Drying the connector without finding what let the water in returns the fault at the next wet spell.
Typically an easy fix. Often worth checking before paying anyone to look.
Some of these codes mean you should stop driving
14 of the 308 codes this can cause indicate a fault where continuing to drive risks damage or is unsafe. Which one you have matters more than the cause does — read the code's own page before deciding.

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.
