If the pressure solenoid valve is stuck in the closed position or the solenoid valve itself is faulty, you can remove the solenoid valve for cleaning. If that doesn't work, replacement is the only option. Below are specific details about automotive trouble codes: Introduction: Automotive trouble codes are codes generated by the vehicle's ECU (Engine Control Unit) after analyzing faults when issues occur. Generally, these codes indicate sensor malfunctions or poor sensor performance, but some mechanical faults cannot be read by the ECU. When a car engine develops a problem, a diagnostic tool will display the trouble code, allowing mechanics to accurately identify the faulty component for repair. Function: Trouble codes are essential conditions checked in the control logic to determine whether certain functions meet control requirements. If conditions are not met, the function may be canceled or restricted, with a prompt to the driver. For critical signals, a backup signal may be provided as a substitute while the function is restricted. In summary, these codes provide the basis for normal control unit operations.
