Code 15 Help?

[phoonTy]

My engine throws a code 15 every six months or so. I usually just pull the fuses, reset the ECM and it goes away for a few months. I'm getting tired of it though. I know it deals with a coolant temp sensor/engine temperature, but that's all I know. Can anyone help me fix it permanently? The truck runs like crap when it throws the code.

As always thanks for the help. Throwing engine codes making a crappy running truck, and finding out your turbo has a bent impeller blade makes me wonder why I'm trying so hard to keep this truck. :-?

Thanks for the diagram. That's way more then I've been able to find. I'll be diagnosing this week sometime.

Will also recommended I find someone with a SimuTech electrical scanner because I may have more electrical problems than that.

certainly helps! gotta love syty.net. :tup:
