I have a 2002 dodge dakota 4.7 parked it one evening next morning wouldn't start but turns over.No gauges working . have replaced pcm,cam sensor,crank sensor( ignition key cylinder it was going bad)replaced pcm cause it was giving me codes 920,921,999 without the p on the dash.At a loss don't know what to do.can anyone help?

 

sorry i think i put it in the wrong forum

 

Check all your grounds in the cab and in the engine bay.


Did you do any work under the cab dash at all?

 

920 is a vehicle speed sensor message from the PCM.
921 is a no distance pulse from PCM.
999 is an error has been discovered.

Those are CLUSTER message - not P codes.

P1698 No CCD messages from the TCM.

Something is killing your CCD bus. Usually it is cam/crank sensor issue. Check for 5 volts present at it. The orange wire is the 5v supply. The black/light blue wire is the ground on both.

It could also be the TCM.

 

have not done any work on the inside around dash but cleaned all grounds under hood

 

yea i wonder if a got a nother bad crankshaft sensor or the tcm is bad .would a bad tcm short the crankshaft and camshaft sensors?

 

i will have to check the power going to them today (the sensors) maybe a wire or connector.

 

It doesn't have to short the cam/crank sensor. It can short out your CCD bus - the computer bus on the truck.

 

it's only getting 1.3 volts at the camshaft plug in.

 

didn't check the crank sensor plug
