Throttle Actuator Control Range/Performance (Bank 2)

The engine computer detected that the throttle control on the right side of the engine isn't responding properly to commands, preventing smooth acceleration control. This involves the electronic throttle actuator and its wiring, which could be stuck, damaged, or electrically faulty. Your vehicle may have reduced power, hesitation, or a check engine light, and should be inspected soon to prevent drivability issues.
