P0CD0: Charge Port Door A Position Sensor Circuit Intermittent/Erratic
What to do
Say which way it is failing — refusing to charge, or refusing to drive — because the same sensor produces both and they point in opposite directions. Check the flap closes fully and cleanly by hand; a door that is not quite shutting is a real cause and costs nothing to find.
What this code means
The charge port door position sensor is reading erratically, which on an outdoor sensor points at water or corrosion. Why the car senses the door at all, and how the two failure directions differ, are at P0CCC.

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.
