So I thought I would be ridding myself of an O2 sensor code, ended up getting rid of my continuosly on Parking Brake light and not the code. I just resurected my 1989 S-10 by installing a rebuilt trans, the truck has been sitting for nearly 5 years. After fixing all the Pack Rat chewed wires I had, and a whole bunch of other issues that I had forgotten about in the last few years. I got the truck running and back on the road. I installed a new O2 sensor during all of the repairs. I got the code 13/SES light on first test run after about 5 miles of driving and pretty much what it does every time I drive it. Yesterday I broke out the VOM and checked continuity to ground, no ground. So I ran a wire from ground and attached it to the body of the O2 sensor via hose clamp since its only a 1 wire O2 sensor. I have continuity to ground now, thinking that would fix my code 13 in fact didn't but it made the Parking Brake go out. Any explanation for this would greatly appretiated.

Ok so the grounding wire didn't end up doing anything. Park brake light is back. Guess its time to buy a 3 wire O2 sensor so I can get rid of the Code 13. Thanks for at least posting 1gmc, thats better than nothing.

So cleaned all grounds that I could find, reset the ecm and the code comes back up. Broke out vom and I'm getting 1.5v off the purple o2 sensor wire from the ecm. I don't think I should be getting any volts off this wire.
