Default P-O483 CODE ANYONE ELSE HAVE THIS HAPPEN

I cycled my key 3 times to see if there where any codes and this code shows up.. I called the dealership and they said its a fan speed code. But I never had a light come on. Wouldnt a light come on for this?

Either a faulty clutch fan, faulty or shorted harness, faulty ECM, or it's an intermittent problem. I'd say there is a short cause the light was on at one point, but the problem corrected itself, and with a few good key cycles, the light shut off. But the code remains in the ECM for diagnostic reasons.

If it comes back on, disconnect the plug and clean the connection. Also find out if the wires were rubbing anywhere and fix as necessary.
