How do you fix a P1753 and P1751 code on your dodge 2500?

Answer 1

crawl under driver side of your truck look up on the tranny and you will see a ttva throttle valve accuator. remove two blots holding it on. push up on it after rotating it out away from the tranny check the linkage moves freely for 45 degrees. make sure the d shaped plastic D shaped connector on the ttva is not cracked. so linkage is good and free moving. now disconnect the electric connector and test pin 5 its numbered in the connector for momentary 12volts when the key is turned on your going to need a helper its right when the key is flipped to the on position if no 12 volt present check your wire harness make sure its not grounded out. if its not grounded out then its 99.9% your ECM has pooped. look on ebay for a vin coded reman unit and hold on to your wallet. if you have 12volts at the connector its 99.9% your ttva has pooped and its also a ride at he Dodge dealer.
