oxygen sensors keep coming back as not ready?

Does the engine temperature gauge stay on cold too long? If you don't have a gauge no worries, if the thermostat is stuck open the OBD2 system will not run through the monitors therefore the oxygen sensor will not be ready. Here is a generic guide to help you step by step with instructions in the diagrams below to show you how on your car:

I don’t believe so I observed yesterday it only took a few minutes for the temperature gauge to start going up.
