i was adjusting some stuff on my TPI motor and i was using a OTC scanner to read the TPS voltage and i adjusted it to .54 walked away and came back to it at 1.04 and this happened like 4 times, so basicly im asking why do you guys think the voltage keep changing? should i just go get a new TPS?

 

set the tps sensor with key on engine off. should not move at all

 

i did about a half dozen times, it even changed fom last night to this AM when i was driving to work, it was .54 when i left and .20 when i got to work


immmmm just gonna buy a TPS
