help with some error codes

Thanks in advance for the help.

Its a 2008 F350 with 148,400 miles. Tuned with Spartan and driven daily on the 150 or 175 tune.

Here's the codes:

P0128 Coolant Temp below Tstat
P0563 System Voltage High
P0625 Generator field terminal low voltage
P1000 System readiness test not complete
U0155 Lost communication w/ instrument panel cluster control module


Recently replaced both batteries and also cleaned the terminals thinking corrosion


Thanks,

Chris

Hmmm, I think you have two items going on here.

First the p0128 could mean..imho, that either you have thermostats sticking open or a sensor is giving a false reading. I'd test the sensor.

The P0563 could be the regulator for the alternator is pushing too much. I'd test the charging system.

P1000 ignore it is because of the other stuff. Probably the same with the U0155.

Check your pcm connection pins to be sure all is cleaned and the pins are in their normal position.

PCM wiring harness is right behide the airbox against the firewall. Pay attention to the way it connects. Has to go back the same way.

It is not that hard or difficult. Just be careful.

As you are looking at the two connectors..the right one is your concern.

you don't want any grease on those pins. If so wipe them off with a kleenex. Try again after that.

If the pins are dry and clean and not pressed in ...are you saying only the manifold code is now showing?

no manifold as well as the low voltage generator. Di-electric grease will not help get a better connection?

yes- voltage at idle is 13.55

MAP- 16psi


Now i did clean the air filter while i had the box out looking at the pcm connectors. I drove it about 6 miles (back to work) without filter installed. This is when the code popped up and now it stays on

I have a friend that owns a Dodge dealership w/ two diesel mechanics on duty. Thoughts on letting them look at it vs. ford. The only issue with local Ford places is premium price for diagnostics ($180). Then premium price for service. and nothing to drive.

Put the air cleaner back on, erase the codes and see what you have.

by leaving the AF out you changed the conditions.

Bet the Dodge place cannot read the codes as they are ford specific.

I did all that and now its going nuts, wait a minute- thats me thats going nuts. Lost turbo earlier, then it came back, then lost all instruments on dash- that was great while driving at highway speeds. Ugh, I give up, its going somewhere tomorrow.

....just wondering though....the belt has squealed a little on startup- wonder if a slipping belt could be the root of the problem?


Thanks for the assistance

Chris

Well don't think the squeaking belt would be the cause.

Sounds like a mess for sure. It is something electrical and I hate electrical stuff! I think you did about as good as anyone.

Got to be some wires/harness somewhere creating the intermitent problems.

Any chance you recently swapped tunes and didn't follow the on-screen directions to a tee?

Also, if you did swap tunes, is the tune you are running compatibable with your DPF situation; i.e. no DPF tune with DPF removed or DPF installed tune with DPF installed? Seems like dumb questions, but it's an easy mistake.

I would give Spartan a call as their world revolves around our trucks and they are pretty quick with suggestions.

Good Luck!! Keep us posted.

here's the followup:


I fixed the map error- guess when i checked pcm connections i knocked the intake hose loose and it was sucking air- whew what a relief.

truck is going to ford dealership for generator/alternator/voltage regulator problem and also to fix the leaky upper radiator hose. I am sure they will do the pcm update so I will have some tuner updates to do.

The Spartan guys (and gals) are great. Quick service and always willing to help answer questions.

Well I guess you can blame some of that on me for telling you to check those connections.

It was worth a shot anyway.
