About P0745

P0745 is a generic (obd-ii standard) powertrain diagnostic trouble code. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

Because P0745 is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The fault code P0745 is set when the Transmission Control Module (TCM) detects a malfunction within the pressure control solenoid 'A' circuit. This solenoid is responsible for controlling the hydraulic pressure in the transmission. A malfunction in this circuit indicates that the solenoid may not be operating as intended, leading to incorrect or erratic hydraulic pressure, which can affect the transmission's shift quality and timing.
