Trying to help a friend out here-


2005 Toyota Camry V6 SE
Automatic

Stock, Stock, Stock



He's got a P2238 code & figured it's the O2 sensor... but I forgot to get a pic of the VIN so I can figure out which V6 engine it has...
3.0L
3.3L


But I did a quick search on AutoZone and found this using DENSO as a replacement-

I'm thinking there's one on the top exhaust header [front & back], then probably one right on the Y-connector BEFORE catalytic converter and one AFTER the catalytic converter


So a TOTAL of FOUR


But I tried search for a pic confirming the O2 locations verifying if 4 or 3...


I didn't wanna create a new account on a Camry site, so I thought someone here has experience on a Camry V6


Thanks!
