OBDII Codes P0134 and P2234
 

Hi, sorry to make this my first post, but I'm a bit desperate out here in Japan.

I have a 2003 Accord EX (V6) that I brought with me from the States when I transferred to Japan. The CEL recently started coming on, so I used my code reader whichcame back with0134 (O2 Circuit No Activity (Bank 1; Sensor 1))and 2234 (O2 Sensor Reference Voltage Circuit/Open Bank 1 Sensor 2). I'm not completely sure what that means...do I need to replace the O2 sensor or is it just a fuse somewhere? I tried to take the easy way out and went to the nearest Honda dealer, but it turns out that Honda Japan "is not allowed to touch privately imported vehicles." Next I went to a private garage and was told that there are four O2 sensors on my car and while the labor would be about $55, each sensor would be $260/each. That said, if I can figure out which part I should buy (if any) online, I can savea great deal of grief and money by replacing it myself.

The car is still running ok, but a bit sluggish.

Please help!!
