i dont see a problem using an aftermarket sensor in this situation. i mean if people are getting rid of the check engine light by simply soldering the wires from the B2S2 to the B1S2 wires, and leaving the bad sensor on the y-pipe, then i doubt that using an aftermarket sensor would do any damage in the near future, or ever.
i am now being quoted about $190 installed, by a local body shop in town...
this is simply to just buy, and install the faulty sensor
i have another question though, is there ANY chance that this could be an electrical problem and my sensor is just fine? or would that be highly unlikely? i mean the sensors have about 80,000 miles on them, its probably just time to replace, right?
