Are they the same part, as in are they interchangeable?
I purchased this from ebay
http://www.ebay.com/itm/4-Pin-Upstream-O2-Oxygen-Sensor-For-Honda-Acura-Civic-CRV-CR-V-AM-32232736-SG336-/251743526942?fits=Year%3A1998%7CMake%3AHonda%7CModel%3ACivic&hash=item3a9d15601e&vxp=mtr
But cant find one for downstream so I'm wondering if they are the same. The same user sells 2 for 30 as well but the same part number (donno why you'd need 2 unless its for up and down)
I just came from etest and I got p0135 and P0141 codes (weird because I scanned the car a week ago and wasn't there)
Thanks guys. I just bought this car for a highway hog and am really enjoying it.

No they are not interchangeable. They have different part numbers. Best thing to do is to get the number off of the old one and do a parts search that way (if its a Denso or NTK sensor).
That's to bad! Throw it away and buy a Denso or NTK sensor. Those cheap ones are junk and probably wont fix your code problem.
What car do you have?

I have a 1998 honda civic dx 1.6...canadian tire and part source wanted $99 for the upstream And 99 for the down... I refuse to pay that.
Where can I find quality ones?

That's how much a quality one cost. Were they Denso or NTK sensors? These are the 2 brands that are the best for Honda's and in my opinion the only option.
What's $99 spread over a year, $8.25 a month.

If you think a good mechanic is expensive, try hiring a bad one
Re: Are upstream and downstream o2 sensors the same?
Both sensors don't normally go bad at exactly the same time.
Check fuse #15 in the dash fusebox, see if it is blown.
Due to wire harness short.
And may have several other codes set for items that share the same blown fuse. ELD, VSS, EVAP, and the alternator may not charge.
Then you can put your original sensors back in, they are probably still better than ebay cheapos

haha true, I only spent $500 on this car and it needs a bit of work, no rust (the previous owners oiled it every year) and its a DX (I dont think people like the DX due to being lowest class)... I'm really not looking to turn around and sell it but I don't want it being a money pit either. I only purchased this to go on the highway and save gas (which its unbelievable at!)

Re: Are upstream and downstream o2 sensors the same?
well, i got a Civic EK3 1999. had D15Z4 which i swapped by D17A Vtec.
the problem is, i did not get any O2 Sensor with my engine. and as its my first honda, i am not sure what or which sensors will work with my engine.
as i need two O2 sensors, upstream and downstream, can anyone help me on it by suggesting the right information,please?
thanks in advance.

Sensor WIRING plug should match the harness used
If using 1999 EK3 ECM and harness you will need sensors for 1999
