Question about Cars & Trucks
Posted by Anonymous on
Good luck with this one you will need to have the tps and the pedal sensor tested as these and the chevy trucks have so many problems with the throtle bodys. ive had a few of these and 90% of the time the throtlebody had to be replaced as you cant replace the tps or other components in the throtlebody.

This is indicating that the TPS Sensor is either out of calibration or defective however it sends dc low voltage to the computer like at idle it is reading its lowest value and when you tag the pedal(WOT wide open throttle) pedal to the metal...it will read its highest just to let the computer know if you are idling, driving slow or really stepping on it, these various TPS readings gives the computer the proper information to allow the different sensors such as the O2 sensor etc. and the injectors how to behalve through electronic voltage signals all the while keeping your vehicles engine running at its top performance for efficientcy and for clean exhaust emmisions.
The shop scanners are the best to use when replacing or resetting the TPS as with the proper testing for any other electronic sensors on your vehicle, these scanners are a bit too expensive for any one to be owning working on their vehicles, it just doesn't seem to be cost effective.
I think you would be better served letting a certified tech take care of this matter for you.
Hopes this helps
