Welcome, I'm Chris (aka Moose).
Check for 5 volt reference voltage to the Brown/White wire at any of the 3-wire sensors, MAP and ICP are 2 to check at. If the 5 volts is there with the key on then replace the PCM. If there is not 5 volts then we need to unplug all sensors getting 5 volts to see if one sensor is to blame. If the 5 volts never shows up then we need to cut this wire out of the PCM. If its still not there then we need to confirm all PCM powers and grounds are good. If so then the PCM is bad.
If you're confused on what to do now. You have already been charged the full question value. It's now time to compensate the tech that helped you. The only way I can continue to work here and help customers is by getting rated. If you're not pleased yet or plan not to rate me. Let me know so I can help more, close the post, or opt out. Please let me know if you're pleased with my help.
So I assume the first part of the test failed, you do not have 5 volts to the MAP or ICP with the key on?
Hello again Chris here,
I am contacting you because the post has not been closed or rated. We have 7 days to get a post rated before it times out. When a post times out, that means its no longer on my active list (if you reply I never know it.) You have already paid the fees to get this question answered, but it appears you're not pleased, or need more help.
Let me help some more. Is there anything else you feel I could offer so you would be pleased with my help. I have the option to call you if that would be better.
