    I have a '03 Toyota Tacoma and the check engine light is on. I pulled the code and received P0136, which is Heated oxygen sensor - bank 1 sensor 2 (H02s12) circuit fault. Could someone tell me what the problem would be and how do I go about fixing it.

    I have the same problem. Check engine light is on with a P0136 code. I replaced both O2 Sensors, ran a drive cycle and got the same code. What else could it be? I've replaced the EGR valve and EGR vacuum modulator 2 years ago because of similar, if not same, codes. Help!
