Ok has anyone seen the TPS volts change by dropping volts at idle in closed loop? I've tried other TPS units. We have a new Snap on scan tool and we are back probing the connector. We set the volts with a meter and at the same time we are watching on the scanner what the ecm is commanding. The volts drop from .42 to .10 .14 then back but the TPS still show .42. I've tried the different ecms. Thoughts??
