P2119 — Throttle Actuator Control Throttle Body Range / Performance

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

About P2119

P2119 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 P2119 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 P2119 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 electronic throttle body combines the throttle plate, the actuator motor, the return spring, and the throttle position sensors into a single assembly that the engine control module both commands and monitors. During key on self checks and continuously while running, the module drives the plate through its travel and verifies that the reported position tracks the commanded position within a tight tolerance and within the expected time. DTC P2119 sets when the throttle body as a whole fails that performance check, meaning the plate does not reach its commanded position, moves too slowly, ove...
