P0135 Hyundai - where is the heated o2 sensor fuse located

Question

I am trying to find where the heated oxygen sensor fuse is located

Answer 1

Hi there,

ECM1 fuse in the fuse box under the hood provides power for the O2 sensor heater. It also supplies the power for the purge control solenoid. If it's blown you would likely have a code for that as well.
