Code P2727 Description

The P2727 diagnostic trouble code (DTC) refers to a problem with the Pressure Control Solenoid 'E' Control Circuit being open or malfunctioning. This component is responsible for regulating the hydraulic pressure within the transmission, which in turn controls the shifting of gears. When this solenoid fails to function properly, it can lead to serious issues with the transmission's performance, resulting in erratic shifting, harsh engagements, or even complete transmission failure.

Common Causes of P2727

  1. Faulty pressure control solenoid 'E'
  2. Wiring issues or poor electrical connection
  3. Low transmission fluid level or contaminated fluid
  4. Internal transmission damage or wear
  5. Faulty transmission control module

Symptoms of P2727

  1. Erratic shifting or difficulty shifting gears
  2. Harsh engagements or slipping transmission
  3. Delayed or prolonged shifting between gears
  4. Transmission overheating
  5. Illumination of the Check Engine Light

How to Fix P2727

  1. Begin by conducting a thorough inspection of the pressure control solenoid 'E' and its wiring harness to check for any visible damage or loose connections.
  2. Test the solenoid using a multimeter to ensure it is functioning within the manufacturer's specifications.
  3. Check the transmission fluid level and condition, topping off or replacing the fluid if necessary.
  4. If the solenoid is faulty, replace it with a new one and clear the DTC from the vehicle's computer system.
  5. Test drive the vehicle to ensure the transmission is operating smoothly and recheck for any reoccurrence of the P2727 code.

Cost to Fix P2727

The cost of repairing the Pressure Control Solenoid 'E' Control Circuit/Open issue can vary depending on the make and model of the vehicle, the location of the repair shop, and the extent of the damage. Typically, the replacement solenoid itself can range from $50 to $200, with additional costs for labor and diagnostic testing. Overall, the total repair cost for this issue could range from $200 to $500, including parts and labor.

  • on my 2009 Toyota Corolla, I changed both solenoids and torque converter as well as the sensor, but the light is on again. Repair shop told me it might the computer. I don't who to trust and what part to change at this point....
