need a resistance reading quick

Can someone get me a resistance reading at the connector to the ccp soleniod on the passenger side of the intake manifold. I'm getting 10ohms i think at the connector side in key to acc. position and 0 through the soleniod itself....but I don't know if 10 is a normal reading or not for the wiring harness.

I went to hop in my car and the reverse lockout wasn't working, then the SES kicked on. I scanned it and it said 26 ccp electrical fault...32 i think for egr electrical and reverse lockout and fans...i know fans work fine and nothing wrong with reverse lockout. I thought maybe that was computer thing so i don't drive with ccp and egr not working. I dunno but any assistance would be great.

Thanks,
Ross

new development

Since I couldn't find anyone to get a reading I pulled the computer out and checked each terminal until I found the opposite end. I got 0 resistance for both connectors...so my ccp and egr are fine. Well I just for kicks jumped the relay on #2 fan and everything is fine as if nothing wrong. So I check all the relays but they are fine???

So now I'm baffled. Hop in and reverse lockout doesn't work, ccp, egr, fan #1 and #2 codes come on. BUT if I clear codes and jumper #2 fan relay everything works normal with no codes. I jumpered all the fans individually and they work like normal. All the relays are working too.

Anyone with an idea? I'm stuck here and I need to get it going. It's dark out now and getting later by the minute.

OH btw when I turn on the a/c and don't have anything jumpered the fans don't seem to come on.
