Throttle valve adapter/potentiometer open circuit short circuit to B+ Throttle valve potentiometer open circuit short circuit to B+ These codes were not cleared.i replaced the coil and leads then replaced petrol relay and temp sensor as well as the maf sensor.problem is still there and getting worst. Can anyone help please

  • Why didn't you address the codes? I'd be checking my throttle body. – jwh20 Dec 28 '19 at 11:17
  • The guy that did the diagnosis left me hanging and said his busy I must wait till he has time.i checked the throttle body cleaned and sprayed with the spray but nothing – Rolland Dec 28 '19 at 12:54
  • It sounds to me that there is an issue with the throttle body position sensor (i.e. the potentiometer). If that's a separate part on this model, you may want to check and replace it. – jwh20 Dec 28 '19 at 14:50
