About P0772

P0772 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 P0772 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 P0772 is set when the transmission control module (TCM) or the engine control module (ECM) in vehicles with integrated control systems detects that shift solenoid 'E' is continuously in the 'on' position, regardless of the control commands. Shift solenoid 'E' is integral to the operation of the transmission, controlling the flow of hydraulic fluid necessary for the engagement and disengagement of gears. When the solenoid is stuck in the 'on' position, it may result in improper gear shifts, an inability to shift out of a gear, or other abnormal transmission behaviour.
