P0925: Gear Shift Reverse Actuator Circuit Range/Performance
What to do
Changes in one direction may be slow or inconsistent. Ask for the actuator current draw to be compared against specification.
What this code means
The reverse-direction shift actuator is responding outside its expected window — slow, or drawing current that does not match the movement achieved. As with P0921, a rising current trend measures a mechanism stiffening rather than an electronic fault developing.
Likely causes
Start here
- Faulty gear shift actuator · specialist
- Worn gear selector linkage · specialist
- High resistance in actuator wiring · moderate
Less common
- Low hydraulic pressure in the actuator system · specialist
- Gearbox actuator calibration lost · 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.
