3.2volts on first O2 with p0420 code?
as an update, it appears the 3.2v is from the air/fuel sensor and that voltage should be OK. Now I'm not sure if the second O2 is supposed to fluctuate or be more steady?- brianinmaine

3.2volts on first O2 with p0420 code?
2008 Corolla with 136k miles. PO said he swapped a hollowed out cat system with one from a junk car. Just got it yesterday, and I hooked up my OTC scanner with live data. The code is p0420, the first sensor reads ~3.2V steady and the second O2 reads between .1 and .9 but changes very quickly...- brianinmaine
