Hi,

 

The TP sensor is integrated into the Throttle Body on your vehicle and not serviceable by itself:

The reason is because yours is fly-by-wire and has an electronic throttle body that receives signals from an APPS(acceleration pedal position sensor) instead of using a throttle cable:

2003 yukonxl can i replace tps myself? flexfuel 5.3 no throttle cable.

Hi,

 

Your engine does not have a separate throttle position sensor. It is integrated into the throttle body.

 

The fly-by-wire system doesnt have serviceable TP sensors or serviceable IAC valves, this includes the flex-fuel system.

okay so your saying i can't fix tis myself, i have to take it to a mechanic shop.
Expert:  Eric replied 8 years ago.

Hi,

 

I am saying that if there is a fault code for a failed TP sensor, the entire throttle body has to be replaced. You can do this yourself, but as I said the TP sensor is not a serviceable item itself- if it fails, the entire throttle body has to be replaced.
