I been having trouble with my catalytic monitor not going to "ready" for my smog check. I have performed alot of drive cycles but it still wont send the ready signal. The mechanic said if it didnt get above 200 degrees the monitor wont perform the test and wont send the signal or the bottom o2 sensor was bad.

I check my coolant temp in normal operating and it stays around 185-190.
Can that or my o2 sensor be bad?

ive driven the car for 600 miles highway and street
