1999 Honda Passport 6 cyl Four Wheel Drive Manual

I have a 99 Honda Passport 4wd, manual, 3.2L, V6. I have and engine code that indicates the O2 sensor 2 in bank 2 is possibly faulty. I have a Haynes manual but it does not show the specific location of the sensor. As far as I can tell there are 3 sensors, 2 on each pipe coming of the engine and one on the drivers side below/past the catalytic converter. How do I know which of these it is to change it?

Hey Lhensel,

Both oxygen sensors that are before the catalytic converters are sensor 1. For example Bank 1 sensor 1 is the first sensor on the side with the number 1 cylinder. Oxygen sensors after the catalytic converters are number 2. For example bank 2 sensor 2 is the sensor after the cat on the opposite side of cylinder.

Hope this helps

Best, Ken
