How hard is it to DIY? Do you have to take the exhaust off to get to the sensor or is it external? It seems like it would be an easy thing to replace but I don't know

4x4Wire - Tech: Time to Replace the O2 Sensor on your 3rd Gen Toyota? I did mine at 100K as a preventative maintenence. Bought the DENSO brand on Amazon. Denso makes the OEM sensor that Toyota will sell you for twice as much. Good Luck.
