Ok, I went and did some snooping around today at my vehicle and the codes I got from the ECU are as follows.

3- MAP sensor

6- coolant temp sensor

10- TA sensor

13 PA sensor

20- electrical load detector

As far as MAP is concerned, I believe I have a bad ground there. The vehicle ran find yesterday and the cooling fan kicked on and never overheated, but then today the car didn't start, just cranked over, so it could be possible that somehow the damn coolant sensor went bad, somehow,........yeaaa, so anyway, has anyone had these problems with thier vehicle or do you think I need to replace the ECU? I can do the field tests on each particular device if I need to, but chances are, they might lead me to a new ECU, oh man, I'm fustrated. OK, maybe someone will have a clear mind. what would your next move be??

Perform the K-Test. This is a show stopper if it fails. Turn ignition ON and test for 5 volts between the MAP Sensor connector reference wire (+) and ground. If it fails, replace your ECM. I don't believe it's realistic to have that many different codes being thrown, unless the ECM is bad.

can you tell me which wire would be the reference wire you can tell so this way I have 2 sets of eyes instead of just mine. thanks!!

from what i see on my diagram i have

white wire on an end
green/white wire in the middle and it has a (-) next to it
yellow/red wire on the other end and it has a (+) next to it
