Back Again, another question for you guys!
I'm not new to the site, I had a post on here back in the summer time regarding a starting issue which Im happy to report got fixed and it was something simple! Now I now have a new problem and I probably know what I have to do but I figured since you guys are pretty smart on here I'd throw it out here for you guys.
First off I have a 2006 Cobalt 2.2 liter 4 banger, I got 112,000 miles on it and I have had to sink some money into a long the way, all the miles are highway - driving back and forth to work.
Haven't had any issues w/ the car as of late, the only thing done to the car was a O2 sensor was replaced. Which was done over 2weeks ago
Yesterday my check engine light comes on, just out of the blew it comes on, strange part is there is absolutely no issues w/ the car, its starting fine, its running fine, it's driving fine, so strange noises or bangs, or clangs or anything. So I bring it over to my buddies house since he is pretty mechanical and has a code reader, so its pretty simple to do you just plug the code reader into the module on the driver side right under the steering wheel to the left and it gives out the code and you go look it up and your done.
Well it didn't work that way, when the code reader was hooked up (side note, this code reader has been hooked up to my car before and worked fine and the code reader was working fine) there was absolutely no power coming from the module, the reader was dead as can be, tried putting the car into run, still nothing. Took the code reader over to one of his cars, plugged it up worked perfectly fine, went back to my car hooked it up still no power to the reader at all.
So we checked fuses to make sure and none of the major ones were blown out or anything.... tried plugging the code reader up again after checking the fuses still no power to it.... the only thing we could do to clear the check engine light was to unhook the battery for a couple minutes and then plug it back up, after we did that the check engine light went away and it hasn't been back on .... yet. We tried hooking the code reader up after hooking the battery back up and still no power.
The only thing I can do now is just take the car in and get the dealer to hook it up to there machines and get a diagnostic of what's going on, but I was wondering if anyone has had this problem and if so what was wrong? I think this is a two fold problem w/ the module having no power and then the check engine light coming on.
any thoughts or input would be great!
Thanks again guys!
