P2769 — Torque Converter Clutch (TCC) Pressure Control Solenoid Control Circuit Low Voltage

System: Powertrain  |  Type: Generic (OBD-II Standard)  |  Make: Generic

About P2769

P2769 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 P2769 is stored, the module has detected a signal or supply voltage lower than the expected operating range.

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 P2769 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

On vehicles fitted with electronically controlled automatic transmissions, the Transmission Control Module (TCM) or Engine Control Module (ECM) monitors the torque converter clutch (TCC) pressure control solenoid circuit for correct voltage and current response. DTC P2769 is set when the control module detects that the voltage in the TCC pressure control solenoid control circuit is below the calibrated threshold while the solenoid is commanded to operate, indicating a short to earth or a low side driver problem. This prevents accurate modulation of torque converter clutch apply pressure and th...
