Code P0973 2014 GMC Sierra Description
The P0973 diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a problem with the Shift Solenoid Valve 1 Control Circuit having low voltage. In an automatic transmission system, shift solenoids are responsible for controlling the flow of transmission fluid to engage the appropriate gear for smooth shifting. Solenoid Valve 1 specifically manages the first gear shift. When the control circuit detects low voltage, it means that there is an issue with the electrical signal that controls the solenoid, leading to potential transmission problems.
Common Causes of P0973 2014 GMC Sierra
- Faulty shift solenoid valve
- Damaged wiring or connectors in the control circuit
- Malfunctioning transmission control module (TCM)
- Low transmission fluid levels
- Electrical issues such as a blown fuse or short circuit
Symptoms of P0973 2014 GMC Sierra
- Delayed or harsh shifting
- Gear slippage
- Transmission not shifting gears
- Poor acceleration
- Reduced fuel efficiency
How to Fix P0973 2014 GMC Sierra
- Begin by conducting a visual inspection of the wiring and connectors in the control circuit to check for any damage or corrosion.
- Test the shift solenoid valve 1 for proper operation using a multimeter to measure resistance and voltage.
- Check the transmission fluid level and quality, ensuring it is at the correct level and not contaminated.
- If necessary, replace the faulty shift solenoid valve 1 and repair any damaged wiring or connectors.
- Clear the DTC with a scan tool and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P0973 2014 GMC Sierra
