There are alot of variables that go into the equation.

The CTS/IAT at start up ,time & O2 heater & feedback.

By then it has been in closed loop for a while.
Look thru do you have a perameter/PID that says loop status?

Just watch for when the fuel trims start to be something
other than zeros, and note the coolant temp....
