2005 Kia Sportage Oxygen Sensor Fuse?

Question

I installed a replacement oxygen sensor and accidentally plugged it in upside down. Now i get a P0052 Error code "faulty heater" code. Is there a fuse for this that i could have blown? I can't seem to find any fuses that control the Oxygen Sensors.

Hi there,

You likely damaged the new sensor. The power supply is the main relay, if this was bad the vehicle wouldn't run. The fuel pump would not get any power, nor would the computer.
