Code P0796 2017 GMC Sierra Description
The P0796 diagnostic trouble code (DTC) for a 2017 GMC Sierra refers to the Pressure Control Solenoid Valve 3 being stuck off. This code is specific to the transmission system of the vehicle. The pressure control solenoid valve is responsible for regulating the hydraulic pressure within the transmission. When the valve is stuck in the off position, it can lead to a lack of proper pressure regulation, which can result in various transmission issues.
Common Causes of P0796 2017 GMC Sierra
- Electrical issues such as a faulty solenoid or wiring
- Mechanical failures within the solenoid valve
- Debris or contaminants blocking the valve
- Low transmission fluid levels
- Internal transmission damage
Symptoms of P0796 2017 GMC Sierra
- Erratic shifting
- Harsh shifting
- Delayed engagement
- Inability to shift gears
- Decreased fuel efficiency
How to Fix P0796 2017 GMC Sierra
- Begin by conducting a thorough inspection of the transmission system to identify the root cause of the issue.
- Test the pressure control solenoid valve 3 to determine if it is stuck off and not functioning properly.
- If the valve is indeed stuck off, replace the pressure control solenoid valve 3 with a new, functioning unit.
- Clear the DTC from the vehicle's computer system to reset the transmission control module.
- Test drive the vehicle to ensure that the transmission is shifting smoothly and that the issue has been resolved.
Cost to Fix P0796 2017 GMC Sierra
