Toyota Celica throttle stuck wide open while driving on freeway requiring heavy braking to stop on Toyota Celica

Some Toyota Celica owners report experiencing dangerous situations where the throttle becomes stuck wide open while driving on the freeway. This alarming issue can be caused by problems with the throttle linkages, which may lead to unintended acceleration. Additionally, obstructions or build-up in the throttle body can result in the throttle sticking, necessitating a thorough cleaning to resolve the problem. Malfunctions in the throttle position sensor (TPS) have also been reported, and testing it with a multimeter can help diagnose whether it is the source of the issue. Some owners consider using a throttle cable conversion kit to improve operation, particularly in Celicas with carburetors. If these issues persist, it is crucial for owners to seek professional inspection to identify the root cause and ensure the necessary repairs are made, prioritizing safety to prevent accidents or further vehicle damage.
