E34 without O2 Sensor have 1221 Error Code

[shogun]

a 1992 E34 US version without oxy sensor and without cat?
let me know the VIN and I will check that out.
So far I have only seen U.K. and Italian spec cars without cat, as that was an option in these countries in these days, but USA in 1992?
I thought almost all gasoline cars in USA were equipped with cats since around 1975?

VIN- BF97758, in realoem there is O2 sensor and cat, but actually no. The entire exhaust system of the car is all original.
