P0928 Dodge Code - Gear Shift Lock Solenoid/Actuator Control Circuit 'A'/Open
Quick Answer
The P0928 diagnostic trouble code (DTC) for Dodge vehicles refers to a fault in the Gear Shift Lock Solenoid/Actuator Control Circuit 'A', indicating an open circuit. Common causes include Faulty gear shift lock solenoid/actuator: The primary cause of the P0928 code is a malfunctioning gear shift lock solenoid or actuator that has an open circuit, Damaged wiring: Broken or frayed wires in the control circuit can prevent the solenoid/actuator from receiving the necessary electrical signals, Blown fuse: A blown fuse in the control circuit can disrupt the power supply to the gear shift lock solenoid/actuator, causing it to malfunction. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0928 Dodge Description
The P0928 diagnostic trouble code (DTC) for Dodge vehicles refers to a fault in the Gear Shift Lock Solenoid/Actuator Control Circuit 'A', indicating an open circuit. This code typically affects the automatic transmission system of the vehicle. The gear shift lock solenoid or actuator is responsible for preventing the gear shifter from being moved out of the 'Park' position unless the brake pedal is depressed. When this solenoid or actuator fails to function properly due to an open circuit, it can lead to difficulties in shifting gears or even prevent the vehicle from being shifted out of 'Park' altogether.
Common Causes of P0928 Dodge
- Faulty gear shift lock solenoid/actuator: The primary cause of the P0928 code is a malfunctioning gear shift lock solenoid or actuator that has an open circuit.
- Damaged wiring: Broken or frayed wires in the control circuit can prevent the solenoid/actuator from receiving the necessary electrical signals.
- Blown fuse: A blown fuse in the control circuit can disrupt the power supply to the gear shift lock solenoid/actuator, causing it to malfunction.
- Faulty transmission control module (TCM): A malfunctioning TCM can fail to send the correct signals to the gear shift lock solenoid/actuator, leading to an open circuit.
Symptoms of P0928 Dodge
- Inability to shift out of 'Park': The most common symptom associated with the P0928 code is the inability to move the gear shifter out of the 'Park' position, even when the brake pedal is depressed.
- Difficulty shifting gears: The gear shifter may feel stiff or resist movement when trying to shift into different gears.
- Illuminated gear shift indicator: The gear shift indicator on the instrument panel may display incorrect gear positions or remain illuminated when the vehicle is in 'Park'.
- Transmission not engaging: The vehicle may not move when the transmission is shifted into Drive or Reverse, even after pressing the accelerator pedal.
How to Fix P0928 Dodge
- Diagnose the issue: Begin by using a diagnostic scan tool to retrieve the trouble codes and identify the specific cause of the P0928 code.
- Inspect wiring and connections: Check the wiring harness and connectors associated with the gear shift lock solenoid/actuator for any signs of damage or corrosion. Repair or replace any damaged components as needed.
- Test the solenoid/actuator: Test the gear shift lock solenoid or actuator using a multimeter to determine if it is functioning correctly. Replace the solenoid/actuator if it fails the test.
- Check fuses: Inspect the fuses related to the gear shift lock solenoid/actuator circuit and replace any blown fuses with the correct rating.
- Verify TCM functionality: If the issue persists, check the transmission control module (TCM) for any faults or errors. Replace the TCM if necessary to restore proper communication with the gear shift lock solenoid/actuator.
Cost to Fix P0928 Dodge
The cost of repairing the Gear Shift Lock Solenoid/Actuator Control Circuit 'A'/Open issue can vary depending on the specific cause of the problem and the labor rates in your area. On average, the parts for this repair can range from $50 to $200, while the labor costs can add an additional $100 to $300 or more. Therefore, the total repair costs for this issue could be anywhere from $150 to $500 or higher. It's important to consider the specific diagnosis time and labor rates at auto repair shops, which can fluctuate based on various factors. Be sure to get a detailed estimate from a trusted mechanic or dealership before proceeding with the repair to avoid any surprises in the final bill.
