P0930
Gear Shift Lock Solenoid/Actuator Control Circuit A Low
Transmission / shift interlock
Generic OBD-II
Medium
What it means
P0930 means the control module reads a low-voltage condition in the circuit for the gear shift lock solenoid or actuator. This device locks and releases the shifter, so a fault can leave you unable to shift out of Park or into a gear. The engine still starts and runs — this is a shift-interlock circuit fault, though it can immobilize the car until fixed.
Medium
Can I keep driving? The engine starts, but you may be unable to shift out of Park or into a gear — have it checked before relying on the car.
Common symptoms
What you'll notice
- Check-engine light on
- Unable to shift out of Park or into the desired gear
- Gear shift lever feels stuck or locked
- Intermittent or faulty operation of the shift lock
Common causes
Most likely first
- Wiring or connector fault in the control circuit (shorted low or high resistance)Likely
- Poor electrical connection at the solenoid or actuatorCommon
- Faulty gear shift lock solenoid or actuatorCommon
- Blown fuse or faulty relay in the circuitLess often
- Faulty gear shift or transmission control module (rare)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check the related fuses and relay first.
- Inspect the shift lock solenoid connector and wiring for damage, corrosion, or a short to ground.
- Measure the control circuit for correct voltage and resistance with a multimeter.
- Replace the gear shift lock solenoid or actuator if it reads low with wiring and power confirmed good. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P0930?+
The engine runs, but if you can't shift out of Park the car won't move, so have it diagnosed before depending on it.
Can I just clear P0930?+
It will clear, but the low control-circuit reading returns until the solenoid or wiring is repaired.
