Code P0973 Description
The P0973 diagnostic trouble code (DTC) refers to a Shift Solenoid 'A' Control Circuit Low. This code indicates that there is an issue with the electrical circuit that controls the shift solenoid 'A' in the transmission. The shift solenoid is responsible for regulating the flow of transmission fluid to engage the appropriate gear for optimal performance. When the control circuit is detected to be low, it means that there is a problem with the electrical signal that controls the solenoid, which can lead to improper shifting or failure to shift altogether.
Common Causes of P0973
- Faulty shift solenoid 'A'
- Damaged wiring or connectors in the control circuit
- Malfunctioning transmission control module (TCM)
- Low transmission fluid levels
- Power supply issues to the solenoid
Symptoms of P0973
- Harsh or delayed shifting
- Transmission slipping
- Vehicle stuck in a particular gear
- Limp mode activation
- Illumination of the Check Engine Light
How to Fix P0973
- Begin by conducting a thorough inspection of the wiring and connectors in the shift solenoid 'A' control circuit to check for any damage or corrosion.
- Test the shift solenoid 'A' to determine if it is functioning correctly. If it is found to be faulty, replace it with a new one.
- Check the transmission fluid levels and top up if necessary. Low fluid levels can also cause shifting issues.
- Inspect the transmission control module (TCM) for any signs of damage or malfunction. If needed, replace the TCM.
- Clear the DTCs from the vehicle's computer system and test drive the vehicle to ensure that the shifting issues have been resolved.
