I Have a 1993 Toyota Celica GT 2.2L when I unplug the oxygen sensor while the car is running. No engine light, no difference. When I plug it back up no engine light no difference. Is this not functioning right. Because all the cars ive seen trigger the engine light when the sensor is removed, bad, or unplugged. In my car is does nothing

Its suppose to trigger the CEL. BTW what's the problem with the snitcher-
