Answer 1

You may have to use a different scan tool . when you disconnect the battery just to clear a code you would loose the pinion factor . P2074 is for the MAP and the TPS and what does not set a code is a speed sensor A faulty speed sensor is not going to allow a cruise control and would make it the engine jump like a motor mount problem
