About P0765

P0765 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.

When P0765 is stored, the module has detected an open (broken or disconnected) electrical path in the monitored circuit.

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 P0765 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 P0765 is set when the transmission control module (TCM) or the engine control module (ECM) in vehicles with integrated control systems detects an open circuit in the shift solenoid 'D'. An open circuit condition means there is a break in the electrical pathway needed for the solenoid operation. Shift solenoid 'D' is responsible for controlling the hydraulic fluid flow that facilitates gear engagement and disengagement. An open circuit prevents the solenoid from receiving electrical power, thus impacting its ability to operate and potentially leading to shifting issues or the ina...
