Gear Shift Lock Solenoid/Actuator Control Circuit A/Open
What it means
P0928 means the control circuit for the gear shift-lock solenoid is open — there's a break in the wiring or the solenoid winding itself. This solenoid is what keeps the shifter locked in Park until you press the brake, so an open circuit can leave the shifter stuck in Park or, on some designs, able to move without the brake. The engine still starts normally; if you're locked in Park, use the shift-lock override to get going, then fix the circuit.
Can I keep driving? The engine still starts, but the shifter may be stuck in Park (or unlock without the brake); get the interlock repaired so you can shift normally.
Common symptoms
What you'll notice
- Shifter won't move out of Park, or moves without the brake pressed
- Check-engine light on
- Non-responsive shift-lock mechanism
- Intermittent shift-lock behavior
Common causes
Most likely first
- Open or disconnected wiring in the solenoid control circuitLikely
- Faulty gear shift lock solenoid/actuatorCommon
- Blown fuse feeding the solenoidCommon
- Loose or corroded connectorLess often
- Faulty shift-lock control moduleLess often
How to diagnose & fix
Work through it in order
- Check the fuse feeding the shift-lock solenoid.
- Test the solenoid control circuit for continuity — an open is what sets this code.
- Inspect the connector at the solenoid for damage or corrosion.
- Replace the shift-lock solenoid/actuator if its winding is open.
- Clear the code and confirm the interlock releases with the brake pressed.
