No.8 cylinder Code

[Im_Strokin_ur_Cummins]

I have been getting a low cylinder contrabution code for cylinder #8 every time i plug my MODDIS into it. I have changed the injector twice and still keep getting this code any ideas on why this keeps happening?

It's a faulty code that always comes on. It's because of the CPS. You can order a black CPS from dieselsite (I think???) that helps. But there's nothing wrong with your injector/cylinder.

Found some places that still carry the Black CPS for you...

I believe Bob(Guzzle) and Clay @ Rifraf ar both out of the black CPS's, but if you have an international dealer/supplier near you, you should be able to go in and ask for a "Black CPS for a T444E" Don't say powerstroke!


Here's a good read about the CPS's, I only tested with the grey and black Ford units, but my results were consistent with the OP's in the thread.

At first there was an issue with the cylinder/injector but after changing the injector and knowing it was good had me woundering especially after we put the 2nd one in and still getting the code. My dad has the same truck as me year and everything except his is 2wd. He ran the Moddis on his and doesnt get the code. Not really too worried about it but it one of those little piss me off things lol

Read the info in the link, like I said, it will make more sense. I was getting the code for #3 and #8 reading "Low" and the truck ran great. I changed the CPS to the Ford Black one, tah-dah, no more #3/#8 codes.
