yes, the simulator did work in keeping the CEL off. but with one stipulation if you have state emisions and that is that the O2 heater shows up on the scanner as a pending code even though the simulator keeps it from tripping the CEL light. hope this helps...

skip buying a new sensor unless the old one is bad. i have an aftermarket cat as well. put the money into the simulator instead. it seems that a lot of aftermarket cats trip the dreaded p0420 code (on foreign cars as well) even though they would pass an emisions sniff test. i'm in MN and we don't have emmisions testing...
