P0930 code meaning
Gear Shift Lock Solenoid/Actuator Control Circuit A Low
What P0930 means
The voltage on control circuit A of the shift lock solenoid stays below the expected level, typically a short to ground or a driver output pulled low. No manufacturer documents this code publicly. FCA uses the sibling codes on the same brake transmission shift interlock (P0928 BTSI Control, P0931 on the 2016 Grand Cherokee). CARB requires output components to be checked for circuit continuity and shorts, while a safety-only system may be exempt, which is why these faults often do not light the MIL. P0928 is the open, P0931 the high fault, P0929 the plausibility fault of circuit A; P092C is the low fault on circuit B. Depending on the design the selector stays locked in Park or is no longer locked at all.
P0930 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0930
- Selector lever stuck in Park although the brake is pressed
- Selector can be moved out of Park without pressing the brake
- Shift lock override slot needed to move the lever
Common causes of P0930
- Most likelyShift lock control wire chafed through to ground in the console or under the carpet
- PossibleShorted turns in the shift lock solenoid coil
- Less likelySpilled liquid in the shifter area causing leakage to ground
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0930 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. |
| 30 | The exact fault in that area. |
What to do next
- Note P0930 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 P0930
What does P0930 mean?
P0930 means "Gear Shift Lock Solenoid/Actuator Control Circuit A Low". The voltage on control circuit A of the shift lock solenoid stays below the expected level, typically a short to ground or a driver output pulled low. It is a generic code, so it means the same on every make.
Is it safe to drive with P0930?
P0930 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will P0930 fail an emissions test?
P0930 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 P0930 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P0930 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
