Re: Insp Failed - Cat and 02 Sens - Not Ready
a drive cycle is the time it takes the ecu to complete all of its functional checks... some checks have to be performed at certain steady speeds, some after a certain speed range has been sustained for a certain period of time, it usually is vehicle specific but most vehicles drive cycles are similar, if you do city and hwy driving often i think it would be safe to say you have completed a drive cycle... maybe talk to the tech about the "not ready" part and what he thinks it means...
