All the codes are for S2 -- behind the Cat.

Check wiring and connectors first.

so the two sensors that are closest to the rear of the car are bad? are those the primaries or

secondaries? i thought the two toward the rear of the car were the primary and determined A/F ratios etc., and the two toward the front were for emissions purposes.
