Question
Hi...I own a sentra spec v 2003 , its engine was replaced because of a recall...after this ive been having ptoblems with my throttle body but the thing is that it was replaced for various failures (no accelaration-limp mode , engine turns off ) ..after it was replaced i drove fine for about two weeks and then the problem came back... service engine light is on and the codes are related to the throttle position sensor . I really dont know what to do sith this persisting problem... anything you can do to help will be appreciated.

Answer
Hi there, has the TPS been checked by a qualified auto technician? If so, what exactly are the trouble code numbers? It's possible that the TPS is  faulty, not adjusted properly or disconnected, or there is an open wire between the sensor and the ECM. Also, it is possible that the ECM itself had failed.
