P0929 code meaning
Gear Shift Lock Solenoid/Actuator Control Circuit A Range/Performance
What P0929 means
Set when the shift lock actuator on circuit A is electrically present but does not respond as commanded, for example it fails to reach the locked or released position. Ford stores it in the gear shift module (GSM): SSM 51057 and 53039 list P0929:77 (commanded position not reachable) on Mach-E, Escape, Bronco Sport, Maverick and Transit, fixed by GSM software or replacement; TSB 25-2045 adds P0929:00, :07 and :9A on 2021-24 F-150 together with a selector that will not leave or enter Park, and checks pin 3 of connector C211. Ford shows the wrench lamp, not the MIL. P0928, P0930 and P0931 are the pure electrical faults of circuit A, P092B the same fault on circuit B.
P0929 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 1.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0929
- Wrench or transmission warning lamp on
- Selector will not leave Park or will not go back into Park
- Clicking from the shifter or a selector that does not stow or unstow
Common causes of P0929
- Most likelyGear shift module software that misjudges the actuator position (Ford reprogramming bulletins)
- PossibleWorn or binding lock actuator inside the shifter assembly
- PossiblePoor pin fit or damaged pin at the shifter connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0929 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 29 | The exact fault in that area. |
What to do next
- Note P0929 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0929
What does P0929 mean?
P0929 means "Gear Shift Lock Solenoid/Actuator Control Circuit A Range/Performance". Set when the shift lock actuator on circuit A is electrically present but does not respond as commanded, for example it fails to reach the locked or released position. It is a generic code, so it means the same on every make.
Is it safe to drive with P0929?
P0929 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0929 fail an emissions test?
P0929 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P0929 to fix?
Difficulty: medium. A typical repair takes 0.5 to 1.5 hours of work. This is a job for a workshop.
Will P0929 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
