I need a TPS and the ones you can buy from autozone and other discount auto stores don't seem to work for me. Where can i get a TPS for cheap with as good of quality as OEM?

 

Why isn't it working?

Make sure to request correct TPS.
TPI and TBI throttle postion sensors are different.

Are you getting improper voltages during the installation of the new TPS?

 

I have tested and retested the voltage and it is always different with the current TPS. It is only a year old and so i tried to get a new TPS from autozone again and it was still throwing the same codes. I don't know what to do anymore. Mainly just want to put a better quality TPS in to eliminate the possibility of the TPS being bad. One day it will throw a code for High voltage and the next day it throws a code for low voltage. Don't know what to do anymore and am getting very frustrated. Aaaahhhhh.

 

When you test the TPS output voltage, you should also test the TPS reference voltage (5.0VDC) across the sensor to make sure the new TPS even has a chance of delivering the correct signal. With a wandering reference voltage, it wouldn't matter who made the TPS.

 

Heed the words of Vader!!

 

As far as i remember the reference voltage was always correct.
