First of all I have a 2000 Accent GL completely stock and a few months ago (I'm such a procrastinator! LoL) my check engine light came on so I take the car to a local autoparts store, they hooked it up to a computer and tell me the code, I find out its the O2 sensor, I replace it, and check engine light went off. A week later it came back on again, I repeat the routine but this time, the code is different and turns out to be "Oxygen Sensor Heating" Does anyone know exactly what this is? The freakin hyundai dealership is completely dumbfounded or rather just plain dumb. Thanks for any help guys!
