Default P650 and P1670 after Intense PCM and 180 stat install

After installing the new PCM and stat, I ran my Bonneville down to the dealership for the CASE learn for the P1336. I also found out that the SWPS is out. After the Case learn, the tech said that these two codes came up. Also noticed that the temp guage was right at 200-205 degrees. This doesn't seem right. I called Intense to see if there is something up with my PCM. I am waiting for a call back from them later today or tomorrow. I have seached the codes and come up with either loose pins at the PCM or relays/fuses loose. The only connection I pulled loose was the battery to swap the PCM. Does anyone know the pin connection for the MIL circuit at the PCM so i can check it?

Here'* the 650 code. https://www.gmforum.com/obd-ii-trouble-shooting-153/p0650-286007/

Check over the connections and fuse. If that'* all OK, it could be a faulty PCM. Do you still have your stock PCM? If so, put it back and see if it corrects the problem

I'd be pulling the pcm connector and looking at the pins. Sounds like one or two pushed back and aren't contacting as they should.

If I pull the PCM loose, will I need to have another CASE learn? Or can I just pull the grey covers loose on the harnesses and check?

You will not need to do another CASE learn. Just pull the plug and inspect them, both the plug and the socket end.

Going out to check it now, should I take the negative battery cable loose?

I only found 1 blown fuse for the cigarette lighter. Pulled the PCM harnesses loose and checked all the pins and the sockets. Didn't find anything out of the ordinary. Put the negative cable back and now its fixed!!! Guess I'm changing the SWPS now, plus a new O2 sensor and fuel filter. Thanks guys!

Do you have a problem that leads you to replace the fuel filter?
