everything on the jeep works 100%, never had one single NSS problem. I am just trying to fix the transmission code that is sending the ECM to post a CEL.
i did noticed if you KEY on, put the trans in N, clear the CEL, start in N, then it will drive park reverse N with out any CEL, and will only reappear if you shut down then restart in either N or P.
changed the Purge solenoid with a JY one and no diff. going to try cleaning the contacts and or inspecting the wires
