OD light flashing

So I pulled up a few codes I was hoping someone could shed some light on. I know rhe circuit have no clue where to start looking. I've got Brake cleaner and dielectric grease I was planning on cleaning all sensors. So these are from koeo#23 & #67 and #29 from continuous memory thanks for all help

OK code 23 is mostlikely you didn't hold the accelerator pedal to the floor while testing.... code 29 is VSS code 67 is MLPS possibly out of adjustment

Make sure the Mlps is adjusted right.. clear code and don't worry too much.. make sure that connector is clean at the Mlps

If it's out of tune, it'll run like crap and mpg will not be as good.

See Post #4 for MLPS testing... Code 67
https://www.ford-trucks.com/forums/2...-the-mlps.html


Here is the Pin Out of the connector so you can make sense of the numbers listed in Post #4



This could be caused by the shift linkage not being adjusted properly when the Reinstalled your Transmission...

Well you were right they did install a chiller on the outside. I didnt see it until today when i was changing the fuel filter. So I've drove like 100miles since i got it back with the rebuilt transmission. All was good until today I go to leave the shop I drive for i jump out of my truck jump out. I lock the gate get back into the truck put into gear nothing. Same thing as last time i get nothing in all gears and when I try to put it into drive while running it grinds. When its off i can get put into gear. 4x4 selector is not showing upbon dash anymore either. Im gonna make sure i get the whole new rad this time.
