Pressure Control Solenoid E Control Circuit High
This code means that the car's computer detected a problem with a part that helps control the pressure of the transmission fluid. It's like a switch that isn't working right, making the car's brain think the pressure is too high.
The P2730 code indicates that the transmission control module (TCM) has detected a high electrical condition in the circuit of the pressure control solenoid E.
The pressure control solenoids in an automatic transmission regulate the hydraulic pressure to the clutches and bands to ensure smooth gear shifts. Solenoid E is one of these solenoids. A 'high' circuit condition means there is too much voltage being detected, which could be due to a short circuit or a fault in the solenoid or wiring.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the pressure control solenoid E for proper operation.
• Check the TCM for faults.
• Replace the faulty pressure control solenoid E.
• Repair or replace damaged wiring or connectors.
• Replace the transmission control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Transmission Control System
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic for a thorough diagnosis.
Check if the vehicle's powertrain warranty covers transmission repairs.
This code has been commonly associated with vehicles experiencing transmission issues due to solenoid failures.
High – This issue can lead to transmission failure if not addressed promptly.
Driving with transmission issues can be dangerous and may lead to further vehicle damage.
• Vehicle at operating temperature
• Transmission in gear
The pressure control solenoid E is located inside the transmission, typically mounted on the valve body.
Q: Can I drive with a P2730 code?
A: It's not recommended to drive with this code as it can cause further damage to the transmission.
Q: How can I prevent a P2730 code?
A: Regular maintenance and inspections of the transmission system can help prevent this code.
