Trying to figure this out for him as the warranty is getting ready to expire. Any help would be appreciated????

I did these tests on my 2003 3500 with 5.9 cummins it came up with no c codes but thes p codes

P0148 High Pressure Common Rail (HPCR) Fueling Error Checksum

P0201 Injector #1 Control Circuit

P0206 Injector #6 Control Circuit

does this mean i have bad injectors??? or and injector pump going bad???

So, what are you asking? It does not necessarily have to have P codes.

The C code definitions are in the DTR wiki, I believe...

Anybody know????

My bad, I read your post wrong. I was backwards.

I don't have time to do it now (it's my morning) but if no one gets to you today, PM me and I'll look them up.

It would help if you filled out your sig so we know what mods you have. Instructions below...

Hope that helps a little.


If you have programmers, return the truck to stock, disconnect the batteries for about 20 minutes. This will reset the computer, so if it's just a glitch, you could fix it with this.


I would also advise, if this does not help you, to post this problem over in the 3rd gen section where more people will be more likely to find it.

Plus, do you have any gauges? FP or RP? What are they reading if so?

WHAT DOES FP OR RP MEAN??

fuel pressure before injector pump. rail pressure pressure between injector pump and injectors

I tried the "turning the key to on 3 times" and got nothing...not even a "done" ... no biggie..

Then i did the
All the idiot lights lit up like a Christma tree, and the gauges went to their max, and backed down(counter clockwise) in steps.
I got the same C44.7 code as high bid. Got a couple other that didnt make and sense.. S11.6 and a ,28.1 ... what the heck is a ,28.1???
http://i126.photobucket.com/albums/p107/r1otis/5-4.jpg
http://i126.photobucket.com/albums/p107/r1otis/4-1.jpg

Well I got C codes, but I can't decipher them, they seem to read different than ya'lls. When mine did the gauge test and finished it displayed "C-Codes" then

A4 08
A7 15
AA 15
B8 01
00 00

Can I get some help here fellas???

Bump..........
