The 2019 500 apparently has no O2 Sensor. At least I can't find it
Without an O2 sensor how is the Fuel Injection controlled?

I looked at the parts diagrams for other Rangers and I don't see an O2 sensor on the 570 or 900 either.
Without an O2 sensor, its an open loop system and it can't compensate for improper fuel mixture.
What gives?

The 500 and 570 do not have O2 sensors and therefore have essentially temperature and pressure compensated carbs


The 900 does have a O2 sensor
