Default o2 sensor heater not ready
I gone through the drive cycle, and all the other sensors are ready except the o2 heater sensor, I thought this sensor was readied at a cold start while idleing with the a/c on.

Anything will be helpful !

It may take a few drive cycles to get everything set. My experience with emissions readiness has been that the EGR and O2 heater codes may take up to 3 complete cycles to get ready.

This may be a stupid question but does it have to be a complete drive cycle, as the heated sensor is checked at cold start, or should I know if it has readied itsellf 5 minutes after a cold start?

You could try a few cold starts to see if it completes. I say 'a few' because I have never had it pass on the first try.
