Very helpful stuff. With a check engine light on, I couldn't get the 2002 Ram 1500 smogged. I got the same code fault from a local mechanic who scanned it and said the computer needed replacing. I found this thread, checked that fuse and sure enough, that fuse was blown. The check engine light stayed on until I disconnected the battery, I drove the truck until the sensors all reset and no check engine light. Then it passed smog with no problems.
