My 06 5.9 is throwing everything a me. It was driving fine yesterday then started to spit spudder and run like junk. I pulled some codes off it it and they are

U0019
B210d
B212d
U0168
U0164
U0184
C2100
U0002
P0148
P2149

From my research i know alit of these are voltage problems. Im going to throw new batteries on it today and check connections to see if that helps at all. Any other recommendations? Also when i check my injectors what ohm should they be reading.

Thanks in advance

Ignore the U/B/C codes

P0148 is FCA (Fuel Control Actuator) Fuel delivery to be specific so it could be pump related.
P2149 is injector related, could be bad injector solenoid coil or bad injector harness/Valve cover gasket.

I would start with ohming the gasket/harness.

Ok so when i test it what reading should i be getting?

steelblitzkrieg

For the injector at the solenoid it should be below 1 ohm.

I don't recall if the harness adds much resistance.

Ok thank you very much i will do that today

To test the harness do i have to unhook it from the injectors?

steelblitzkrieg

If you want to test the harness alone, yes. You can test the harness and each of the injectors as a circuit which is still helpful to determine if it's something in that circuit causing the issue.

How do i test this harness? Sorry haha im not a wiz

steelblitzkrieg

You need the wiring diagram so you know which two leads to check for each injector/harness strip. Try using the search function at the top of the page. I'm in Cali, so I'll be on the road shortly and won't be home until late (Kids practices, etc.). Hopefully someone else can chime in to get you moving along in the meantime.

#6 injector testing at 1.8 ohms. I think i found my problem. Thanks man its much appreciated.

it is very easy to just change the solenoid and not have to remove the injector. i think most people are using a deep 1 1/8 socket, i used one size smaller and a dremel tool to make the socket fit perfect but we run a fleet and have changed several of them. go to ebay, there are two vendors selling them. the problem is a bad design where the coil connects to a ring by press fit during build. no new ones have failed so i think they may have it fixed.

So should i just change the solenoid or the enitre injector?
