I have been getting a mixed input on which o2 sensor it is....

The code is for p0141 "Bank 1 Sensor 2" o2 sensor

Can anyone confirm if it is before cat (front) or after cat (rear)?

Also, can I use aftermarket for cost savings?

Which brand would you recommend?

I was thinking Bosch/Denso 4-wire universal.... TIA

Secondary (after CAT). This is one of the few parts I would ONLY use a Honda/Acura OE.

Thanks for confirming. Where should I get the least expensive Honda/Acura OE parts for this?
