it's gone! I've had a P1102 and a P1107 that would not go away. Dealer attributed it to a stuck check valve, reset it and happily took my hundred-odd dollars. Problem came back after a few weeks. I bought my own OBD-II reader. I've replaced the O2 sensors and MAF, that wasn't it. Checked the relays, checked the fuses. Checked all the wiring. No problem found. I got my DMV notice that I need a smog, so out of desperation, I cleaned/checked the grounding lug in the rear trunk. The **** thing was loose. I cleaned the contact area with sandpaper and re-tightened. Ground point 8 is to the left of the ECM Ground point 9 is to the right, I think.

It's been 4 days... no CEL, no pending codes according to my OBD-II reader. I haven't gone this long CEL free. I promptly got a smog check at my local gas station, I didn't want to tempt faith.

Hope this helps anyone out there with a O2 sensor heater shorted to Battery plus issue.
