How can I fix the engine code P0838 and P0837? The first is "4WD Switch Circuit Low" and the second is "4WD Switch Circuit Range/Performance" I have not had any problems while in 4WD but after changing back to 2WD, the engine light will flash and lose power under a constant sputter until I stop and so the key dance to reset things. Then it runs fine. Also I have codes P0122, P1490, P1489, P0300, P0301, P0305, P0306, and P0455. I have the list of what they all mean for a 2004 grand cherokee laredo 4.0 v6, but it may as well be written in brail. Lol Any suggestions? Dont really have the $$$ to let a shop fiddle with it for god knows how long and I usually work on my own anyway, just wanting to know if there may be a short cut or something small that may cause all these codes. Maybe an easy fix.
have the same problem?
