2002 Hyundai Elantra GLS 2.0L MIL Lamp on
this 2002 elantra gls has a code po133 stored, but all components seem to be operating fine. The o2 heater voltages are correct and it's response to w.o.t. is above 850 millivolts and when we lean out the engine it drops to about 200 millivolts. Just wondering...
