So.... I replaced all 4 of my sensors like 9 months ago... Denso OEM replacements, soldered in (and I'm not a hack, I know what I'm doing. They were all soldered and shrink tubed, then one large shrink tube around the whole bit...)
And one thing to note... You do not have to take the seat out. I just moved mine all the way forward, yanked out the heater duct, and voila! there it was.
But my car just failed emissions for the B2S2 P0161 DTC... WTF?
Do our cars have heater circuit fuses? Some cars have fuses for the O2 sensor heaters, and it's as simple as replacing the fuse... Anyone?
EDIT: Found out we don't... I gotta do some wire testing now...
Changed out my b2s2 o2 sensor, cleared the code with my reader, but CE light reappeared after 15 minutes of driving. Any ideas anyone?
