P2757 Fault Code

P2757 OBD-II Trouble Code Short Description

Torque Converter Clutch Pressure Control Solenoid Control Circuit Performance/Stuck Off

What does trouble code P2757 mean?

The P2757 fault code refers to an issue with the Torque Converter Clutch (TCC) Pressure Control Solenoid, which is crucial for controlling the engagement and disengagement of the torque converter clutch. This solenoid regulates the pressure applied to the clutch, affecting vehicle performance and efficiency. When this code is triggered, it indicates that the solenoid's performance is below expected standards or it has become stuck in the 'off' position, leading to potential drivability issues.

Symptoms

What are the symptoms of the P2757 code?

When the P2757 code is present, you may notice:

  • Poor fuel economy due to the torque converter not engaging properly
  • Slipping or hesitation during acceleration
  • Increased engine RPMs without a corresponding increase in vehicle speed
  • Potential overheating of the transmission due to inefficient operation.

Causes

What causes the P2757 code?

Several factors could cause the P2757 code, including:

  • A malfunctioning TCC pressure control solenoid
  • Electrical issues such as short circuits, open circuits, or poor connections
  • Low transmission fluid levels or dirty transmission fluid
  • Mechanical issues within the transmission that affect solenoid operation.

Possible Solutions

How to fix P2757?

To address the P2757 code, consider the following steps:

  • Inspect the TCC pressure control solenoid for proper operation and replace it if needed
  • Check all electrical connections and wiring related to the solenoid for damage or corrosion
  • Ensure the transmission fluid is at the correct level and in good condition; change if necessary
  • If no component is defective, the issue may require a more in-depth evaluation of the transmission system.
