Hey hows it going everyone? Im new to this forum, hopefully able to get some answers. I have a 2005 grand cherokee 4.7. i have a code P0481 and myself and my mechanic cant find or fix the problem. I changed the fan and the relays and still the light goes on. He pulled out the distribution box and put it back in and the light shut off long enough so i can inspect it. Im wondering if i should just change the distribution box and the ecm to fix the problem.
