Hey guys,

I just checked my codes today just for snicks and grins.
I found 3 codes:
P0201- Injector #1 control unit
P0202- injector #2 control unit
P2146- Bank 1 (cylinders 1-3) Shorted High Low

Anyone have an idea on what causes these codes?
They all sound like their all tracking back to one problem, whatever that is.

i dont notice anything different in the truck, other then an odd idle, but the trucks done that since day 1.

I installed a boost bolt for the boost gauge this weekend and when i did, i unpluged rail pressure sensor to get access to the forward most intake bolt. I forgot to plug it back in and started the truck. Obviously, the truck didnt like that too much. It ran for about 5 seconds before i shut it off and fixed the mistake.

That, to me, sounds like it could have caused the code. Will this code clear its own or will i need to clear it myself?

If thats not a cause, what could be? Doesnt the ECM control the injectors?!

I sure hope i dont have to replace my ecm to cure the problem.

Thanks guys!!

 

You should be fine. I would not worry about it too much... I have done similar things. The code will clear itself.
