What do i do if my oxygen sensors disconnected on my toyota tundra 2004 limtited edition model

It usually takes a short time for your "Check Engine" light to come on if you lose input from the sensor ... perhaps it was not off long enough to trigger the alarm. If you get an Oxygen fault the engine usually will go into the Rich setting to avoid damaging the engine ... of course your performance and mileage may suffer

You will need a scan tool to turn off the codes.
