Question

I would like to know witch converter it is

Answer 1

Hi there,

This is the front bank of the engine closest to the radiator. The code P0430 is for the bank 2 catalytic converter, and the P0140 is for the bank 1 O2 sensor, sensor 2. So this would be the O2 sensor AFTER the catalytic converter on the bank closest to the firewall.
