Re: All 4 O2 Sensors Bad?
After debating on diagnosing my electrical issues, I realized that a professional would be better suited for the job. I found a guy in Fremont, CA that charged $80. His report found that it's actually a problem with the PCM. He's saying that, although the 02 sensors and heaters are good, the heaters aren't getting the proper signal. He then quoted me $650 to replace it.
I have searched ebay for used pcm's and they seem to be going for about $50. Does anyone know how difficult it is to replace? It seems to be lodged inside the firewall, but I don't want to just rip it out without any input from people with experience. Thanks.
