02 Sensor
 

I've got a CEL on, I can't remember the code, but was told I needed to replace the 02 sensor. They said it was bank one, sensor 2. I'm assuming that's the one that's after the cat.

Question is, where is the best place to get one? The parts store quoted me $130 bucks, and that sounds a little steep, or am I wrong?

2001 Tiburon - 5 Speed, bone stock.

The cheapest place I found was the Hyundai dealer of all places. It was $20 cheaper than at parts stores.

universal 02 sensors work 2 if it's a 4 wire,

2 for heater..white
1 for ground..gray
1 for signal..black

just cut the connector off the old oem sensor, splice it to the universal one and install..done.
