the distributer has a lead to the ecm to tell the fuel injector when to open and close. the hall effect switch detects a load on the distributer i.e. acceloration. and adust the spark and fuel accordingly, normally if the service engine light doesnt read a code 21 and the spring in the tps is springing back into pos. then the tps is good.
