Hey, I drive a 2002 WRB WRX. My car's throwing the CEL for the front o2 sensor. I got a replacement sensor from Advanced Auto and had it installed. The CEL keeps coming back on. I've got a couple questions and am looking for some advice.
I've heard there's a chance that the o2 sensor I got could be busted. What are the chances of that and should I look into that first?
I've also heard that o2 sensors from Advanced have a habit of not working well with WRXs, any input on that?
I've called the dealership and to get them to even look at the car it's $80, if it's simply an o2 sensor it's another $250 from there. That seems kinda ridiculous to me.
If the sensor itself isn't throwing the CEL (if the sensor's fine) what else could be tossing that code?
Thanks in advance, any advice would be appreciated.
