P0930 Fault Code

Gear Shift Lock Solenoid Circuit Low

• What does that mean?
• Symptoms
• Causes
• Solutions

The P0930 fault code indicates an issue with the gear shift lock solenoid circuit in your vehicle. This circuit is crucial for ensuring that the gear shift lever is locked in place unless the brake pedal is depressed. A low signal in this circuit can prevent the vehicle from shifting into gear, posing a safety risk and hindering your ability to drive effectively.

• The gear shift lock solenoid is responsible for locking the transmission in 'Park' when the ignition is on.
• This fault code points to a potential electrical problem in the circuit, which may involve the solenoid itself, wiring, or connectors.

What are the symptoms of the P0930 code?

Common symptoms associated with the P0930 code include:

• Inability to shift the vehicle out of 'Park' without applying the brake.
• Unusual noises when attempting to shift gears.
• Warning lights on the dashboard, such as the check engine light.
• Intermittent or complete loss of the ability to change gears.

What causes the P0930 code?

Several conditions can lead to a P0930 code, including:

• A defective gear shift lock solenoid that cannot operate correctly.
• Damaged wiring or connectors that affect the electrical signal.
• Issues with the transmission control module (TCM) that may not be sending the correct signals.
• Low battery voltage or poor ground connections that impact electrical performance.

How to fix P0930?

To resolve a P0930 fault code, the following steps are typically recommended:

• Inspect the gear shift lock solenoid and its wiring for any visible damage or corrosion.
• Test the solenoid with a multimeter to confirm it is functioning within specifications.
• Repair or replace any damaged wiring or connectors that are found during inspection.
• If necessary, check the transmission control module for faults and reset the system to ensure proper function.
