P0973 is a diagnostic trouble code that indicates an issue with the “A” shift solenoid control circuit, typically due to low voltage.
P0973 Shift Solenoid “A” Control Circuit Low
Code symptoms P0973.
– Delayed or rough shifting
– Transmission slipping
– Erratic or unpredictable shifting
– Transmission not engaging in gear
Causes of the code P0973.
1. Faulty shift solenoid “A”
2. Electrical issues such as a short circuit or open circuit in the shift solenoid “A” control circuit
3. Corroded or damaged wiring connections in the shift solenoid “A” circuit
4. Engine control module (ECM) failure
5. Low transmission fluid level
Code Solutions P0973.
1. Inspect the shift solenoid “A” for any damage or debris that may be obstructing its functionality. Clean or replace the solenoid as needed.
2. Check the wiring harness connected to the shift solenoid “A” for any signs of damage, such as fraying or corrosion. Repair or replace any damaged wires.
3. Test the shift solenoid “A” using a multimeter to ensure it is functioning within the specified parameters. Replace the solenoid if it is faulty.
4. Inspect the electrical connectors leading to the shift solenoid “A” for any loose connections or corrosion. Ensure the connectors are securely in place and clean as needed.
5. Use a diagnostic scanner to reset the fault code and clear the shift solenoid “A” control circuit low error. Monitor the vehicle for any recurring issues to ensure the problem has been resolved.
