elgigante Posted July 6, 2014 Share Posted July 6, 2014 Would running a single wire non heated 02 sensor (universal) work on my 3 plug ea82? I understand I have to splice but will I get a code? Link to comment Share on other sites More sharing options...
skishop69 Posted July 6, 2014 Share Posted July 6, 2014 I don't believe the ECU software was written to monitor the heater circuit. That wasn't required til the late 90's. I know when I disconnected the O2 on my XT for testing, it only set the O2 code. The system was designed for a heated O2, so you will most likely have some runability issues while the vehicle is reaching operating temp. If you have emissions in your area, there is the possibility it won't pass. Personally, I wouldn't do it. Put the correct O2 in. Link to comment Share on other sites More sharing options...
