This summary uses the existing diagnostic information shown in full below.
This means that the car's computer is having trouble talking to a part that helps change gears. It's like trying to call a friend and the phone line is down.
The transmission control module (TCM) has detected a low voltage or open circuit in the shift solenoid B control circuit.
Shift solenoids are responsible for controlling the flow of transmission fluid to change gears. Code P0976 indicates that the electrical circuit controlling solenoid B is experiencing a lower than expected voltage, which may be due to a wiring issue, a faulty solenoid, or a problem with the TCM.
• Check Engine Light is on
• Transmission may not shift properly
• Poor fuel economy
• Faulty shift solenoid B
• Open or shorted wiring in the shift solenoid B circuit
• Malfunctioning transmission control module (TCM)
Transmission Control Module (TCM): A computer that controls the transmission's functions.
Shift Solenoid: An electromechanical valve that controls fluid flow in the transmission.
• Use an OBD-II scanner to confirm the presence of code P0976.
• Inspect the wiring and connectors related to shift solenoid B for damage or corrosion.
• Test the shift solenoid B for proper operation using a multimeter.
• Repair or replace damaged wiring or connectors.
• Replace the faulty shift solenoid B.
• Reprogram or replace the transmission control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord
• Toyota Camry
• Ford F-150
• Regular transmission fluid changes
• Routine inspection of transmission wiring
• Avoiding harsh driving conditions
Transmission Control Issue
• Avoid driving the vehicle until the issue is resolved to prevent further damage.
• Consult with a professional mechanic for accurate diagnosis and repair.
Check with the vehicle manufacturer for warranty coverage on transmission components.
This code has been associated with electrical issues in automatic transmissions, often requiring wiring repairs or solenoid replacements.
Moderate – Should be addressed to prevent transmission damage.
Driving with transmission issues can be unsafe and may cause further damage to the vehicle.
• Engine running
• Transmission at operating temperature
Shift solenoid B is typically located inside the transmission, attached to the valve body.
Q: Can I drive my car with a P0976 code?
A: It's not recommended to drive with this code active as it can lead to transmission damage.
Q: How do I reset the P0976 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is resolved, the code should not return.
