Can someone explain to me why it is that I'm having so many issues with the rear o2 sensor, but none with the fronts...? Yes I do have pre-cat deletes. Does that mean o2 sensors are more likely to go? The elbow that Richie hands out was working up until this point; it's been almost a year with any cel. I've had this one for about a month. P0159, Bank 2, Sensor 2 - I'm assuming rear cat, sensor near the bottom? Anyone know a way to diagnose if it's bad or just in need of an adjustment (can you clean an o2 sensor)?

Oh and yes, I've reset the car previously - codes comes back on 3 times.

Help?

Thanks!

 

PS for IHC,

Matt, I tried pm'ing you to continue our conversation on the matter, but your inbox was full - just a heads up! CLEAR IT!

 

Please post a follow-up when it gets solved for the prosperity of searchers.

 

Will do. But you don't have a solution for me inaccurate? You always have an answer to everything...I'm a little disappointed haha

 

Good one

I have nothing insightful except... if it was me, I would just go ahead a purchase a new O2 sensor to see if that fixes it.

The sensors are not adjustable or cleanable.

Hopefully, throwing some $$ at it will help.

its the front bottom. and no you can not clean it. you will need a pcm update. also cat converter is most likly on its way out.

 

meh, that was useful! haha thanks inaccurate!

 

Oh by the way, with these types of sensors, is there really a difference when going aftermarket? O'Reilly's has one for like...50 bucks. OEM costs around triple, I think?
