P0928 code meaning
Gear Shift Lock Solenoid/Actuator Control Circuit A/Open
What P0928 means
The module that drives the shift lock (brake transmission shift interlock, BTSI) sees no continuity on control circuit A, so it cannot reliably release the selector from Park. FCA/Chrysler uses the code as P0928-00 BTSI Control: bulletin 08-072-14 (2013-14 Ram 1500, 2014 Durango with 8-speed) and 21-034-15 (2015 Chrysler 300 rotary shifter) name it when the selector will not leave Park or the knob turns without the brake applied; the cure there is a new electronic shifter. P0929 is the plausibility fault, P0930 and P0931 the low and high faults of circuit A, P092A the same open fault on circuit B. The driver usually cannot shift out of Park until the fault clears or the manual release is used.
P0928 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0928
- Selector lever will not move out of Park even with the brake pressed
- Problem may disappear after the ignition is switched off and the modules go to sleep
- Rotary or electronic shifter can be moved without the brake applied
- Shift position flashes or a message asks to return the selector to Park
Common causes of P0928
- Most likelyInternal fault in the electronic shifter module, often logged together with P0607 (documented by FCA)
- PossibleShift lock solenoid coil open
- PossibleBroken wire, poorly crimped or pushed-out terminal on the shift lock circuit
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0928 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. |
| 28 | The exact fault in that area. |
What to do next
- Note P0928 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 P0928
What does P0928 mean?
P0928 means "Gear Shift Lock Solenoid/Actuator Control Circuit A/Open". The module that drives the shift lock (brake transmission shift interlock, BTSI) sees no continuity on control circuit A, so it cannot reliably release the selector from Park. It is a generic code, so it means the same on every make.
Is it safe to drive with P0928?
P0928 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0928 fail an emissions test?
P0928 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 P0928 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. This is a job for a workshop.
Will P0928 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
