P2366: Cylinder 12 Pressure Sensor Circuit
What to do
As P2348.
What this code means
The pressure sensor inside cylinder 12 has failed its circuit checks — the last cylinder the standard numbers, so this family belongs exclusively to V12 engines. The whole P2348 picture applies: direct combustion measurement, glow plug integration on diesels, inference as the graceful fallback.
Likely causes

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.
