Hey everyone,

A couple of quick questions:

1) Can some one tell me what a p2146 code means in English?

2) I have been told that my truck has Spicer axels and there is no
locker available for them. Is this true?

 

I think it has to do with low voltage to the injection system. might want to check out all of your plugs going to the injectors


EDIT; found it p2146 = "Fuel Injector Group A Supply Voltage Circ/Open"

check this out also. https://www.dieseltruckresource.com/...ad.php?t=81936

 

And your truck has AAM axles (American Axle and Manufacturing), and I don't think there is a locker kit...

 

could also be an injector. i had the p2149 and turned out i had a shorted injector.

 

They are AAm 10.5 in front and an AAM 11.5 for the rear. Try doing a search for lockers for those axles. I am pretty sure there are a couple of options for them.

 

its the AAM 9.25 front, the 10.50 and 11.50 are rear ends.
