P0888 Dodge -

Question

So the check engine light can cause the low or no voltage code? Right now i have these codes present with engine light on..P0700. P0731. P0732. P0867. P0868. P0888. P1790. And something that says 79H/121 un documented code.... This is on a 02 4x4 Durango 4.7

Answer 1

P0700 Transmission fault detected MIL light requested on

P0731 Geat ratio error in first gear

P0732 Gear ratio error in second gear

P0868 Line pressure low (transmission)

P0888 Relay output always off

P1790 Fault immediately after shift

When all theses code occured , was the TCM relay removed? If not then you go after P0888. clear the code. As long as you have a P0888 you can expect a transmission problem,  This would be a electrical problem dealing with the TCM relay
