P2829 — Pressure Control Solenoid K Performance (Shift Solenoid Valve SLS)

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

About P2829

P2829 is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Toyota vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

When P2829 is stored, the module has detected a plausibility fault — the measured value is in the electrical range but is not consistent with expected operating behaviour.

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 P2829 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

Pressure control solenoid K, identified on Toyota transmissions as shift solenoid valve SLS, is a linear solenoid that regulates hydraulic pressure to the clutch and band apply circuits so the module can control shift feel and clamping force. Unlike a simple on and off shift solenoid it is current controlled, and the module varies the current through it to raise or lower the regulated pressure according to engine load, throttle position, fluid temperature, and the shift in progress. DTC P2829 sets when the module commands a given pressure but the resulting shift timing, pressure feedback, or g...
