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

About P2106

P2106 is a generic (obd-ii standard) powertrain diagnostic trouble code recorded for Holden vehicles. 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 P2106 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 Engine Control Module (ECM) continuously monitors the throttle actuator control system and related inputs for plausibility and correct operation. DTC P2106 is set when the ECM detects a fault in the electronic throttle control system or a related engine management system that could affect safe throttle operation. In response, the ECM commands a reduced throttle opening and limits engine power as a protective strategy, rather than because of a direct fault within the throttle actuator motor circuit itself. When set the vehicle goes into a reduced power or limp mode with limited throttle res...
