Need O2 sensor advice.
 

So I bought a 1994 Camry XLE V6 with 88k miles and the check engine light came on after I bought it. One Hundred dollars later the dealer tells me I need a new O2 sensor and they'd put it in for $480. I told them that was crazy. The maintaince invoice says "Found Code P0135- Vehicle needs new O2 Sensor, Bank One Sensor One. So I should be good if I buy a new sensor and have it installed right? What worries me is that in the maintaince records there is an invoice that says the "front bank O2 sensor" was replaced, is this the sensor? Should the sensor really be going bad after only 40k miles?

thanks,
