Primary O2 Sensor

Meant2Live · Apr 24, 2013

Hey guys
I've got a 2001 Accord MT with a f23a2 . Car has been acting VERY sluggish when cold, and recently I shorted the 2 diagnostic pins below the dash[I don't have an OBD2 port] and I got an error code
41.............P0135,P1166,P1167.................. ....Primary heated O2 sensor

I've been looking around for a replacement O2 sensor and all I can find around here are Bosch and the generic stuff. Denso is the OE, and after looking around I found that 234-4620 is compatible with the f23a1 and the f23a5. Would it be compatible with the f23a2 which I I have? I will have to buy it via Amazon since I can't find it anywhere else. Hence, with international shipping and the waiting time, I want to be sure about this.

The emission norms in India is pretty lenient, and that's why I'm pretty sure that its not a SULEV.
Any pointers? Suggestions?

Is the F23a2

Ulev vtec, vtec, or non vtec?

If vtec or non vtec that part number should work fine.

Don't know if india has ULEV vtec.

TH F23a4 is ULEV, cause It's what i have and the sensor was over 120$.

EDIT

Rockauto also looks like they ship.
Use the same part number UPSTREAM DENSO

Except, We don't use the A2 i believe the A5 is non VTEC the A1 is the Standard and the A4 is the Ulev.

f23a2 is vtec. Highly confused about ULEV or non-ULEV. Thats the only thing keeping me from placing an order

The A4 is ULEV, If you open your hood and your valve cover has a big *** ULEV on it, then its ULEV if not then go with the VTEC model. The Denso number you gave us.
