Question

1999 Hyundai Accent/Verna with code P0141, what is the best solution?

Answer 1

HI there,

This code indicates the ecm has determined there is a problem with the O2 sensor heater on bank 1, sensor #2. Typically with this code if you replace sensor 2 it will resolve the issue. Sensor 2 is the one AFTER the catalytic converter.
