2015 4010 wont run when cold and o2 sensor connected

[kmadsen30]

I have a 2015 Kawasaki mule 4010 4x4 that wont run more that 5 seconds when the engine is cold and the o2 sensor is plugged in. once I disconnect the sensor it runs and has lots of white smoke out of the exhaust. once it warms up I can plug the o2 sensor in and it will run fine. I swapped the sensor and didn't get any change.

Is the engine air coo led or water cooled?

[kmadsen30]

Its liquid cooled. Also I misspoke, it's not the o2 sensor it's the air pressure sensor.

Coolant burns white, you may have a bad head gasket.

 What exactly does that sensor do? Can you run it without the sensor?
