I too need to buy O2 sensor. The OBDII scan says that Bank 1 Sensor 1. Does this mean that I need to buy only one sensor or do I need to replace both ??

Think I need to buy OEM type one. Also, which one is preferrable ?? Denso Or Walker ???

 

thanks!My front O2 sensors have been bad for more than a month now. Hope it did'nt damage my cat. converter.

 

they are still the original o2 since I bought my car 10 yrs ago. tried to buy at autozone but expensive

 

Yeah if you call them they should be able to help you figure out which ones to get. When I talked to them, they said that you're only paying for name to get the Bosch ones, but that's up to you. The main choice is universal or OEM; the OEM come with the plug, while the universal might need you to splice a couple wires. But they (and plenty of other people on this forum) can answer that much better than I can.

 

the OEM are plug and play so to speak....but if u have any wiring knowledge u can use the universal ones

 

Denso or walker ??? one is costlier than the other, so is the costlier of better quality and life ?? thanks
