Question

2009 Nissan Armada with code P0734. Could I have a bad speed sensor and get a po734 code or is it something else

Answer 1

HI there

It is possible there is an issue with the revolution sensor, however most of the time it will set a code if there is a problem. If the transmission fluid is low or dirty it can cause this code as well as some mechanical issue with the transmission.
