both o2 sencers have been replaced...no check engine light and still wont ready moniters......please help

Hello, setting monitors can be a tricky thing to accomplish. Which monitors have not set yet? Keep in mind you have to drive the vehicle at least two drive cycles, for one things staying at about 55-60 mph for maybe 15 minutes -- steady. There is a whole routine that the vehicle is looking for to set monitors, but I can tell you 95% of the time I have success setting cruise control and driving for 15 miles at 56 miles per hour. Then shutting of the vehicle and doing it again. For more information, read this RepairPal article: https://repairpal.com/drive-cycle-issues

Perhaps if you posted the exact trouble code numbers that prompted you to replace the 02 sensors we could further assist..
