You're in Mexico, correct? If so......
Then the emissions standards may not be the same there as they are here. The reason that the post-cat oxygen sensor is there is just to act as a monitor for convertor efficiency and degradation. This is true on all OBDII(on-board diagnostics) vehicles. All 1996 and later US vehicles are OBDII and therefore have the rear sensor. I wouldn't be too concerned about it.
