Ideas for you when your vehicle is in "Reduced Engine Power Mode" When the ECM detects a condition with the TAC system, the ECM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions: • Acceleration limiting--The ECM will continue to use the accelerator pedal for throttle control, however, the vehicle acceleration is limited. • Limited throttle mode--The ECM will continue to use the accelerator pedal for throttle control, however, the maximum throttle opening is limited. • Throttle default mode--The ECM will turn OFF the throttle actuator motor and the throttle will return to the spring loaded default position. • Forced idle mode--The ECM will perform the following actions: - Limit engine speed to idle by positioning the throttle position, or by controlling the fuel and spark if the throttle is turned OFF - Ignore the accelerator pedal input • Engine shutdown mode--The ECM will disable fuel and de-energize the throttle actuator. The tac system is the throttle actuator control If you have no idea what its mean then let the local dealer or repair shop check it out for you. It'll not be a quick fix for you to do so let them handle it..

Liver above is correct. Anything to do with the APP(Gas PEdal) or Throttle Body Sensors, it automatically goes into Limp mode so to speak. Reduces engine power & other things. Prevents what those clowns with those Toyotas tried to say went bad with them & acceled out of control
