P0CF6: Control Pilot Circuit High
What to do
As P0CF3 — try one other charge point and cable to establish whether the fault is the car or the equipment, then have the pilot voltages measured.
What this code means
The Control Pilot circuit is reading above its valid range, which usually means an open circuit — the car is not loading the line at all, so the charge point sees an unconnected state and never energises the cable.
What the Control Pilot is and how the handshake works are at P0CF3.

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.
