Hello all

I just got a CEL today and its a P1164. I was going to throw a a/f ratio sensor at it and see if that code goes away. I want to eliminate that first because the a/f ratio sensor in there now has 295k miles on it. But when I search for an a/f ratio sensor for a 2.3l ulev I find 2 Denso part numbers that claim to work
234-9025 and
234-9014

Its CA emissions fyi. Can anyone clarify this for me because I dont want to get the wrong sensor.. Thanks in advance everyone.

Actually I just looked at the emission label and it says I have a Heated O2 sensor not an A/F ratio sensor..

Its the upstream sensor im talking about here, just so you know thanks.

I thought ulev accords used wideband 02 sensors.
