Hi,
That is an exhaust leak. If the smoke is coming from where the sensor is located, make sure it is tight. If it is tight, remove it and inspect the threads on it. Also, inspect the exhaust manifold for cracks. Note that there is a chance it is leaking where the manifold meets the cylinder head.
Check these and let me know what you find. I will further direct you once we determine the source of the leak.
