honda accord oxygen sensor

Dear All:

I have my check engine light on. The code says the upstream oxygen sensor is wrong.

However when I look for new o2 sensor online, the price for engine F23A1 and F23A4 are very different.

Unfortunately my car's engine is F23A4. Could I use a cheaper oxygen sensor for F23A1 instead?

Thanks ,

The short answer is no. These items have to be exact or you will never get rid of the CEL.

Thanks for the reply. I will use the one for the F23A4.

Now, in market, I could find two main brand: Dosen and Bosch.

For Dosen I could find the right part for F23A4, but in Bosch's website, I could find the specified parts number for F23A4 engine.

Any suggestion on looking for the right parts through google?

It turns out that I am in the wrong Bosch website. Also the cross reference could help me find the right Bosch part # if I know the Dosen's number.

Problem solved, thanks.
