I replaced my coolant sensor the relay for my electric fan, still my engine lights on and codes still there. Code 1491 telling me my relays bad. It is good my guess is that my PCM is bad. Checked it with code reader it tells me my PCM is good. I still think it is bad my PCM. Is there any other ways to make sure my PCM is good or bad? Also, is there a in line fuse for fan or PCM? Please help.
have the same problem?
