P0927: Gear Shift Reverse Actuator Circuit High
What to do
Expect a set of gears to become unavailable. Ask for the actuator winding to be measured directly.
What this code means
The reverse-direction shift actuator circuit reads above its valid range — an open circuit or a short to supply, which the module cannot distinguish between.
Likely causes
Start here
- Open circuit in actuator wiring · moderate

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.
