So after not having cable TV or internet at home I have been reading my Chilton DSM manual!
Now I was reading on the TPS sensor adjustment trying to trouble shoot the surging issues I have always had even before turbo charging the car. I read that the TPS sensor with engine off and throttle closed should read .5 volts +or- .02. I went outside and turned on the key and went into the "Sensor Check" on my NEO and saw that the TPS signal via the NEO is at .62 to.68 volts in this condition with not running and throttle closed. It was jumping between those readings and not a steady reading. When the throttle was fully depressed the reading was now at 4.88 volts and holding steady +or- .01. Now while the car is running and sitting at an idle, according to the "Throttle Percentage" it jumps from 0% to .2% constantly. Now dissregarding the fact the car is turbo'd, and also a 1.8 94 5-speed. Does this diagnosis sound like a bad TPS sensor or is the variable of voltage sound like it's good, and just not properly adjusted? I will have to adjust the ISC motor as well as the NEO once I adjust the TPS sensor. Any thoughts or experiences?
FYI- I do have leaks in the throttle shaft when leak testing at 15psi, however Red1991tsi is rebuilding me one capable for boost as we speak. Just an FYI.
