Part Number A/F sensor and O2 sensor

I have scanned the threads related to P1135 and have figured out that my issue is the A/F sensor (aka front O2 sensor) located in front of the cat. The threads also cover how to change the sensor, it looks fairly easy except finding the end of the wire. The one thing I couldn't find was the part numbers to order the correct sensors! I have a 2001 V6 4wd. I am not sure if I need Denso 234-9002 or 234-9003 for the front sensor. The back is 234-4189, I think. Does anyone know for sure? The 9003 is $130.21 at Amazon, the 9002 is $135.08 and the 4189 is $73.49. I want to make sure I am getting the right parts since I am buying over $200 worth of parts online. Thanks y'all!

Thanks dude!!! I need the manual version and can get both on Amazon for $203.70. Hope it fixes my P1135. The check engine light is on sometimes and off sometimes. Makes me wonder if it is a loose wire but after 123k miles I might need to replace them anyway. Thoughts?

That is the same code for your issue. Check for a loose connection first, then replace the sensor(s).
