P0152 2/1 02 Sens Shorted To Voltage

Unplug it, and probe the connector, see if you get 12 volts (or 5 volts for that matter) where you should not.

 

Well I cleaned the throttle body, iac, etc. it was filthy nasty mess. I have never seen a nastier air filter either. There was also some oil in it. Didn't make much of a difference, but it couldn't have hurt anything. I'll check the 02 sensor voltage next. I do appreciate all the help. Now if I can figure out how to use my new multimeter. Lol
