The P0931 trouble code indicates that there is a high voltage condition detected in the gear shift lock solenoid or actuator control circuit “A”. The gear shift lock solenoid or actuator is responsible for preventing the shifting mechanism from moving out of park without the brake pedal being depressed. A high voltage condition in this circuit can prevent the gear shift lock solenoid or actuator from functioning properly.
P0931 Gear Shift Lock Solenoid/Actuator Control Circuit “A” High
Code symptoms P0931.
1. Unable to shift out of park.
2. Difficulty shifting out of park.
3. Intermittent or inconsistent ability to shift out of park.
4. Check Engine Light illuminated.
Causes of the code P0931.
1. High voltage supply to the gear shift lock solenoid or actuator control circuit “A”.
2. Faulty gear shift lock solenoid or actuator.
3. Wiring or connector issues in the gear shift lock solenoid or actuator control circuit “A”.
4. Corroded or damaged terminals in the gear shift lock solenoid or actuator control circuit “A” connectors.
Code Solutions P0931.
1. Check the voltage supply to the gear shift lock solenoid or actuator control circuit “A” using a multimeter. Repair any issues with high voltage supply.
2. Inspect the gear shift lock solenoid or actuator for any signs of damage or malfunction and replace if necessary.
3. Check the wiring and connectors in the gear shift lock solenoid or actuator control circuit “A” for damage or corrosion. Repair or replace any damaged wiring or connectors.
4. Thoroughly inspect the terminals in the gear shift lock solenoid or actuator control circuit “A” connectors for corrosion or damage. Clean or replace any affected terminals.
