jinxed45 Posted January 20, 2006 Report Share Posted January 20, 2006 Well, technically I passed my smog test according to the numbers but my "MIL" failed (Service Engine Soon light). Pulled the codes, P0146 seems to be the only one affecting emissions. O2 Sensor Bank 1 Sensor 3, simple.. replace it right? Well.. I have had this light for a while, I even changed the Bank 1 Sensor 3 with an ACDelco O2 sensor, brand new at PepBoys. The light never went off, the PepBoys guy said "We changed it, it'll cost more for us to look into it." The mechanic that did the smog test was really cool.. he diagnosed a little bit.. found that the harness that supplies power to the O2 is receiving 12 volts of power (which is correct). SO... if it's not the O2 Sensor itself, or the wires.. what is it?! Computer? 1997 Cadillac Eldorado ETC 130k Link to comment Share on other sites More sharing options...
