This summary uses the existing diagnostic information shown in full below.
This code means that a part in your car's transmission, like a tiny robot, is supposed to help change gears smoothly, but it's stuck and can't move properly.
The code P0747 indicates that the pressure control solenoid 'A' in the transmission is stuck in the 'on' position, affecting the transmission's ability to regulate hydraulic pressure.
The pressure control solenoid is an electro-hydraulic valve that manages the transmission fluid pressure based on commands from the vehicle's computer. When the solenoid is stuck on, it continuously allows fluid to flow, which can lead to improper gear shifts and transmission performance issues.
• Harsh or erratic shifting
• Transmission slipping
• Check Engine Light is on
• Faulty pressure control solenoid
• Transmission fluid contamination
• Wiring issues or poor electrical connections
Solenoid: A coil of wire that acts as a magnet when carrying electric current, used to control valves.
Transmission: The system in a vehicle that transmits power from the engine to the wheels.
• Use an OBD-II scanner to confirm the code.
• Inspect the transmission fluid for contamination.
• Check the wiring and connections to the solenoid.
• Replace the faulty pressure control solenoid.
• Flush and replace the transmission fluid.
• Repair or replace damaged wiring.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Honda Accord
• Toyota Camry
• Ford F-150
• Regular transmission fluid changes
• Routine vehicle maintenance
• Avoid aggressive driving
Transmission Issue
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic if unsure about repairs.
Check with your vehicle's manufacturer or dealership for warranty coverage on transmission components.
P0747 has been a common issue in vehicles with automatic transmissions, often related to solenoid wear or fluid contamination.
High – This issue can lead to serious transmission damage if not addressed promptly.
Driving with a faulty transmission can be dangerous and may violate vehicle safety regulations.
• Vehicle at operating temperature
• Transmission in drive mode
The pressure control solenoid is located within the transmission, typically accessible by removing the transmission pan.
Q: Can I drive my car with code P0747?
A: It's not recommended to drive with this code as it can cause further transmission damage.
Q: How do I reset the Check Engine Light after fixing P0747?
A: Use an OBD-II scanner to clear the code after repairs are completed.
