DTC's 34 and 88

[ccfoshee]

All:

A while back I posted that I had some DTC issues since reinstalling my engine.

I bought and installed a new #5 PMD resistor which fixed part of the problem.

Now, I can start the engine and the SES light will be off, but within about 5 minutes it will come on. It always ends up being 34 (stepper motor fault) and 88 (TDC offset).

This is causing issues as I can't get my timing set properly and cold starts are a pain because of it. I am running around 8.5* desired and my TDCO defaults to -2.02* all the time.

The bright side is, as soon as any temp begins to register on the dash, the truck runs quite well.

Any suggestions?

Thanks.

I think your gonna have to move the pump by hand....to get it within specs.

Then clear all the codes, bring it up to operating temp and try again.

About 1mm at a time......1mm = 2 degrees, "I Think"

Thanks Leo!.....Forgot that. :thumbsup:

He's at -2.02......maybe a 1/2mm cause he's looking for that magic.....-1.50-1.93 TDCO
