Infiniti Code P0745 is a diagnostic trouble code (DTC) that indicates a problem in the Pressure Control Solenoid A. This OBD-II self-diagnostic item is triggered when the Transmission Control Module (TCM) detects an improper voltage drop when it tries to operate the solenoid valve or when an irregularity is detected by comparing the target value to the monitor value. Several issues can cause the code, such as a faulty harness or connectors in the solenoid circuit or a damaged line pressure solenoid valve. To help diagnose the cause of Infiniti Code P0745, it is important to understand the possible causes and solutions.
