in adjusting the TPS, there's a certain voltage it needs to input to the ECU. for my vios, I can monitor the TPS to be at 11% at idle using my OBD scanner. have yet to try to measure the voltage there as it's like a potentiometer (devices used for volume control in stereos)...

if you can find a similar car or just try to google, you can check the voltage, buy a P120.00 multimter from CDR King and you're done :P
