Question

2003 Nissan Altima 2.5L with 168k mi, codes P0720 and P1574: just sensors or tranny probs?

Answer 1

The P0720 is for the revolution sensor on the back side of the transmission. most of the time replacing this sensor resolves the problem.

The other code is for the cruise control, once the 720 is resolved it will normally solve the cruise control issue as well.
