Hey guy's a buddy of mine has a 03 2500 and it throws a P 2146 the guy that scanned it says he has never seen that code. Anybody know what it means? Thanks

 

P2146-FUEL INJECTOR GROUP 1 SUPPLY VOLTAGE CIRCUIT

How's it running?

 

Fuel Injector Group 1 Supply Voltage Circuit

 

It runs a little rough. like it's missing. Has new injectors, But I would have to ask him what else it's doing. Thanks Bill

 

Did this start after the new injectors? Even new can be broken.

 

Yes it did. Any ideas what's causing the code?

 

Bad electronics in one of the new injectors. If you knew which one(s) made up fuel injector group 1 circuit it might help to determine which injector(s).

 

We were talking about infra red temp guns in the towing section and one of the posters said he uses one to find a miss or a leaky injector by checking the temp of each exhaust manifold from the cylinder head. Never tried it but I don't see why it wouldn't work.

 

If you have access to one, that sounds like a GREAT idea.

 

Thanks to everyone that posted. My bud decided to take it back to dodge as they sold him the injectors. They found two that were bad and replaced them under warrenty. Runs great. I will now slink back to the 12V forums were I belong. LOL

 

yeah and don't come back until you own a 3rd gen mister

 

Glad it worked out.
