About P0773

P0773 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 P0773 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 P0773 is set when the transmission control module (TCM) or the engine control module (ECM) in vehicles with integrated control detects an electrical issue with shift solenoid 'E'. This solenoid is vital for controlling the hydraulic fluid flow for the proper operation of the transmission, particularly in shifting gears. An electrical issue could be related to problems in the solenoid's circuitry, such as wiring faults, connector damage, or a malfunction within the solenoid itself. This malfunction can lead to various transmission problems, including erratic shifting, failure to ...
