I'm having a problem with my oxygen sensors, i got it checked out and the computer said that i need a left hook oxygen sensor, where is that?

just re place them all you will be fine.

Typically the computer will return a reading like: bank 1, sensor 1, or bank 2, sensor 2, of which bank 1 is driver's side, sensor 1 is closest to the engine, etc. Never heard of a "left hook" sensor, sounds like a boxing term!

yea just replace them all that should be cheap.........NOT

B1 ON THE MAXIMA IS BY FIRE WALL, B2 IS RADIATOR SIDE

someone told me i need 2 alter sensors wat that? he showed me where they are located but i ask online and know one knows wat i am talking about. they where very thin wire running through my engine. did he say it right or are they oxygen sensors.
