P0930

Gear Shift Lock Solenoid/Actuator Control Circuit A Low

Q: 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.

Q: Can I just clear P0930?

It will clear, but the low control-circuit reading returns until the solenoid or wiring is repaired.

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.
