Question

in my 2000 dodge durango the check engine light is on and I scaned it and the code it apear was P0700 what's that? I just change the speed sensor because I was thinking that would fix the problem but it doesn't ... I need some help

Answer 1

P0700 Transmission fault detected

With this code there should also be another DTC (diagnostic trouble code) along with it, Have the engine as well as the transmission scanned for codes and check the transmission fluid.
