This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the electrical circuit that controls one of the parts in the transmission called 'Shift Solenoid A'. It's like when a light switch doesn't work because the wire is broken.
The P0973 code is triggered when the Powertrain Control Module (PCM) detects a low voltage condition in the shift solenoid A control circuit.
Shift solenoids are responsible for controlling the flow of transmission fluid to the internal clutches and bands, which in turn control gear shifts. The P0973 code indicates that there is an issue with the electrical circuit for shift solenoid A, such as a short to ground or an open circuit.
• Transmission may not shift properly
• Check Engine Light illuminated
• Vehicle may enter limp mode
• Faulty shift solenoid A
• Damaged wiring or connectors
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the shift solenoid A for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the shift solenoid A if faulty.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord
• Toyota Camry
• Ford F-150
• Regular transmission fluid changes
• Inspect wiring and connectors periodically
• Avoid harsh driving conditions
Transmission Control
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic for accurate diagnosis.
Check with your vehicle manufacturer for warranty coverage on transmission components.
This code has been associated with transmission issues in many vehicles, often due to wear and tear or electrical issues.
Moderate – It is advisable to address this issue soon to avoid potential transmission damage.
Driving with a malfunctioning transmission can be dangerous. Ensure repairs are conducted by a qualified professional.
• Vehicle at operating temperature
• Transmission in drive
Shift solenoid A is located inside the transmission, accessible by removing the transmission pan.
Q: Can I drive with a P0973 code?
A: It's not recommended to drive with this code as it may cause transmission damage.
Q: How do I reset the P0973 code?
A: Fix the underlying issue first, then use an OBD-II scanner to clear the code.
