Code P2812 2015 GMC Sierra Description
The OBD-II code P2812 for a 2015 GMC Sierra indicates that there is an issue with the Transmission Control Solenoid Valve 7 Control Circuit being open. This solenoid valve is responsible for controlling the flow of transmission fluid in order to engage and disengage specific gears within the transmission system. When the control circuit is open, it means there is a disruption in the electrical signal that controls the solenoid valve, which can lead to improper gear shifting, transmission slippage, or even total transmission failure.
Common Causes of P2812 2015 GMC Sierra
- Faulty transmission control solenoid valve
- Damaged wiring or connectors in the control circuit
- Malfunctioning transmission control module
- Low transmission fluid levels
- Electrical issues such as a blown fuse or relay
Symptoms of P2812 2015 GMC Sierra
- Erratic shifting patterns
- Hesitation when accelerating
- Decreased fuel efficiency
- Transmission slippage
- Illumination of the Check Engine Light
How to Fix P2812 2015 GMC Sierra
- Diagnose the issue using a scan tool to confirm the P2812 code and identify the specific cause.
- Inspect the transmission control solenoid valve and related wiring for any damage or corrosion.
- Test the solenoid valve for proper operation and resistance using a multimeter.
- Replace the faulty solenoid valve or repair any damaged wiring or connectors.
- Clear the diagnostic trouble codes and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2812 2015 GMC Sierra
The typical repair costs for addressing a Transmission Control Solenoid Valve 7 Control Circuit Open issue can range from $200 to $500, including parts and labor.

Frequently Asked Questions about P2812 2015 GMC Sierra Code
1. What does OBDII code P2812 mean on a 2015 GMC Sierra?
Code P2812 indicates an open circuit in the Transmission Control Solenoid Valve 7 control circuit, which affects the transmission's ability to shift properly.
2. What are the common symptoms of code P2812 on a 2015 GMC Sierra?
Symptoms include harsh or erratic shifting, transmission slipping, failure to engage certain gears, and potentially the illumination of the check engine light.
3. What causes the P2812 code to appear on a 2015 GMC Sierra?
Common causes include a faulty transmission control solenoid, damaged or corroded wiring in the solenoid circuit, or a problem with the powertrain control module (PCM).
4. Can I drive my 2015 GMC Sierra with code P2812?
Driving with this code is not recommended because it can cause further transmission damage and lead to unsafe driving conditions.
5. How do you diagnose the P2812 code on a 2015 GMC Sierra?
Diagnosis involves using a scan tool to confirm the code, inspecting the transmission solenoid wiring for damage, testing the solenoid for proper operation, and checking for PCM-related issues.
6. How do you fix code P2812 on a 2015 GMC Sierra?
Repairs may include replacing the faulty transmission control solenoid, repairing or replacing damaged wiring, or reprogramming or replacing the PCM if necessary.
7. How much does it cost to repair code P2812 on a 2015 GMC Sierra?
Repair costs vary but typically range from $200 to $600, depending on whether the issue is with the solenoid, wiring, or PCM.
8. Can a low transmission fluid level cause code P2812 on a 2015 GMC Sierra?
Low transmission fluid levels can cause shifting issues, but they are unlikely to directly trigger this specific code, which relates to an electrical circuit problem.
9. Do I need to replace all transmission solenoids if code P2812 appears on my 2015 GMC Sierra?
Not necessarily. Only the solenoid associated with the code (Solenoid Valve 7) may need replacement, but a professional diagnosis is essential to confirm.
10. Will clearing the code P2812 solve the problem on a 2015 GMC Sierra?
Simply clearing the code will not fix the underlying issue. The cause of the open circuit must be diagnosed and repaired to resolve the problem permanently.
