Dodge dealer replaced TPS several times for high RPM during idle but they could not fix and I had to pay for the TPS's; A local service shop set the TPS calibration to .2 volts for it to idle correctly (it should be .5 - .6 volts); At .2 volts the check engine light stays on. I need to get the transmission repaired but they will not warranty work with the truck showing a bad TPS. Any ideas what the problem would be.
