I have 2008 CRV and engine light was on.

Error code was P0141: HO2S B1 S2 Heater Circuit Malfuction.

I googled the right one for my CRV, but I am not sure which one it is.

In this forum, I remember that someone recommended Denso product instead of Bosch.

Honda Accord seems like use Denso 234-4733, but Amazon.com shows me that product is not for 2008 CRV.

Can I get the part number, please?

And also, I heard CRV use two O2 sensor; downsteam and upsteam? Do they are same part? or different ones?

More searching on the internet will give you the correct part number.
But, check out the other causes for that code. It could even be a shorted wire, a wet connector or a fuse.
Might look at some other sites also: https://www.civicforums.com/forums/36-mechanical-problems-vehicle-issues-fix-forum/225970-need-help-p0141-o2-sensor-heater-circuit-malfunction-bank-1-sensor-2-a.html
According to the above site, it sounds like that code means the secondary O2 sensor (downstream).
Put "2008 honda crv P0141: HO2S B1 S2 Heater Circuit Malfuction" into the search box in Google, etc.

Here is one link for that part, if indeed, it is the correct one, You would need to check: http://www.ebay.com/itm/Denso-234-4359-Oxygen-Sensor-Air-and-Fuel-Ratio-Sensor-/382108718475?hash=item58f774558b:g:Yn8AAOSw-K9ZJJ-9&vxp=mtr

Let your fingers do the walking. :)

Yes, do troubleshoot a bit further, don't just buy the part listed in the code, especially on older cars it's often something else.
And don't buy parts from ebay and amazon unless you know where it's coming from and what it is. A good source is on-line dealers that sell at a discount. Or bargain with your local dealer.
