P0480 DODGE - What else should I check here??

Question

I have a P0480 code coming up on my van. I replaced the fuse even though it looked ok, and I replaced the relay located between the bumper and the radiator. I unplugged the battery for 15 minutes and it reset everything. The check engine light stayed off for a couple hours of driving but came back on indicating the same code. The cooling fans come on when the proper conditions are met and turn off when the conditions no longer require them, so I really don\'t understand what I am missing here. Everything seems to be working OK and I\'ve replaced the parts I know could be causing the code.

What else should I try??

Thanks!

Please visit the code page, we have just update the "Tech Notes" with a link to a factory service bulletin. The bulletin suggest reprogramming (flash) the ECM to fix the problem.
