SOURCE: P0139 code for a 2003 hyundai elantra. What is this code?

Hi the code P0139 is Bank 1 sensor 2 lambda sensor fault ,possible wiring or sensor fault even if you replace the sensor you need to have the MIL lamp turned off by a Diagnostic machine,it is possible you have another fault such as poor Catalytic converter efficency giving the same fault code ,Would recomend you get the car checked and read the "live" data as the car see`s it to make an accurate diagnosis and cure

Then 1, bulbs are burned out
OR 2, the wiring is faulty.
