P2764 Fault Code
P2764 OBD-II Trouble Code Short Description
Torque Converter Clutch Pressure Control Solenoid Control Circuit Low
What does trouble code P2764 mean?
The P2764 fault code indicates an issue with the Torque Converter Clutch Pressure Control Solenoid's control circuit being too low. This solenoid is responsible for regulating the fluid pressure that operates the torque converter clutch, which locks the engine to the transmission to improve fuel efficiency. A low voltage or current in the control circuit can cause improper functioning of the torque converter clutch, leading to undesired vehicle performance.
Symptoms
What are the symptoms of the P2764 code?
Symptoms associated with the P2764 code may include:
- RPM fluctuations during driving, especially at highway speeds.
- Engine stalling or shuddering when the torque converter engages.
- Poor acceleration or decreased fuel economy.
- Illumination of the check engine light on the dashboard.
Causes
What causes the P2764 code?
Several factors can contribute to a P2764 fault code, including:
- A faulty Torque Converter Clutch Pressure Control Solenoid.
- Damaged wiring or connectors in the solenoid circuit.
- Low transmission fluid levels or dirty fluid affecting pressure.
- Issues with the transmission control module (TCM) that fails to send the appropriate signals to the solenoid.
Possible Solutions
How to fix P2764?
To resolve the P2764 fault code, consider the following steps:
- Inspect the Torque Converter Clutch Pressure Control Solenoid for faults, and replace if necessary.
- Check the wiring and connectors to ensure there are no breaks or corrosion.
- Ensure that the transmission fluid is at the proper level and is clean.
- If the electrical system is functioning properly, a reprogramming or replacement of the TCM may be required.
