Yes it is normal .this is Toyota spec for nigeria market. This is just to show that it the emission regulation of each country that will dictate the addition of certain component.
it is a pity that our country emission is so lax that it doesn't really demand for oxygen and catalyst as compared to some other advance countries which is why some vehicle are like that .This is story for another day sha.

@autologic, thank you very much for the response. I have been battling with fumes of unburnt petrol in the exhaust and that's what prompted me to check, pls is there anything I can do to correct this. Thank you

I am a strong believer in using data for accurate decision making .However this is beyond DIY stuff, find a techie that can do data analysis of scan data of air fuel ratio(this advance diagnosis ) ,probably the anomalies can be spotted

@autologic, thank you very much, I'll do just that and I will give you feedback
