why is my 2001 golf junk?

it is none of the above. it is electric throttle valve so it does not have a tps

What senses how far open , or how far into the throttle then? Is it carbed? They might call it something different on it , but the PCM still needs input! SO, back to my question , are you able to scan live data?

WASTE of time , but funny..........never mind

i had it scanned and there were 10 different codes saying short to ground. i checked all the grounds in the car changed the whole air intake changed the throttle body. checked that all wires and plugs were tight... dont know where to go from here

Codes indicating 'short TO ground' NOT 'short AT ground'........... A short at a groung TO aground is redundant. LOOK for a power or 'input(signal) wire that is damaged and touching a 'grounding source' in the harness somewhere. The codes indicate which circuit is affected , you will need diagrams of the circuit(s) to properly trace and perform necessary testing. LIVE data will help in pinpointing the sensor(s) affected. APPS1 or APPS2 , ETC TAC etc.
