P0772 – OBD-II DTC

OBD-II DTC P0772 – Shift Solenoid D Electrical

DTC P0772 meaning

DTC P0772 refers to a problem with the shift solenoid D in the transmission system. The shift solenoid is responsible for controlling the flow of transmission fluid, which is essential for shifting gears. When the Engine Control Module (ECM) detects an issue with the electrical circuit of shift solenoid D, it triggers this diagnostic trouble code (DTC).

DTC P0772 symptoms

Common symptoms associated with DTC P0772 may include:

• Delayed or harsh shifting between gears
• Transmission slipping or failing to engage
• Check Engine Light illuminated on the dashboard
• Unusual noises from the transmission
• Reduced fuel efficiency

DTC P0772 causes

Several factors can lead to the occurrence of DTC P0772, including:

• Faulty shift solenoid D
• Wiring issues or damaged connectors in the solenoid circuit
• Low transmission fluid levels or contamination
• Faulty transmission control module (TCM)
• Internal transmission problems

DTC P0772 seriousness

DTC P0772 is considered a serious issue as it can affect the vehicle’s drivability and transmission performance. If left unaddressed, it may lead to further transmission damage, increased repair costs, and potential safety hazards while driving.

How to diagnose DTC P0772

To diagnose DTC P0772, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the code.
2. Inspect the transmission fluid level and condition.
3. Check the wiring and connectors related to shift solenoid D for damage or corrosion.
4. Test the shift solenoid D for proper operation using a multimeter.
5. Examine the transmission control module (TCM) for faults.
6. Perform a road test to observe any shifting issues.

How to fix DTC P0772 step-by-step instructions

To fix DTC P0772, follow these steps:

1. Address any low or contaminated transmission fluid by replacing it.
2. Repair or replace damaged wiring or connectors in the solenoid circuit.
3. Replace the faulty shift solenoid D if testing indicates it is not functioning properly.
4. Check and repair any issues with the transmission control module (TCM).
5. Clear the DTC using an OBD-II scanner and perform a road test to ensure the issue is resolved.

How to erase DTC P0772

To erase DTC P0772, follow these steps:

1. Connect an OBD-II scanner to the vehicle’s diagnostic port.
2. Turn on the ignition without starting the engine.
3. Access the scanner’s menu and select the option to clear or erase trouble codes.
4. Confirm the action and wait for the scanner to complete the process.
5. Disconnect the scanner and start the vehicle to check if the code reappears.
