As the driver of a 2013 ford explorer, you will notice an array of lights and codes appearing on your dashboard over the years. usually, they indicate that it's time for routine maintenance of the fluids and components. in the case of code p0430, however, it means that one of the vehicle's oxygen sensors, most likely the downstream sensor, has registered an undesirable reading. this means that either the catalytic converter or the sensor itself is faulty, and needs to be replaced. replacing the converter can cost you between $ 80 and $ 240 for parts. replacing the o2 sensor can cost you between $ 40 and $ 120 for parts. having the converter replaced professionally will put you out an additional $ 250 to $ 530 in labor.
Code p0430 for the ford explorer indicates that one of the oxygen sensors downstream from the catalytic converter, has an out-of-range reading.
