Why does my GMC Yukon have a catalytic converter?
Catalytic Converter – A catalytic converter is responsible for scrubbing out as much pollution as possible from the Yukon’s exhaust. Over time, they can become clogged. Although, modern catalytic converters are supposed to last the life of most vehicles, it could be there is some underlying problem if it has clogged.
What causes the p0430 trouble code on a GMC Yukon?
There are many things that can cause the P0430 trouble code in your Yukon. Here are the most common ones. Oxygen Sensor – The P0430 codes is thrown when the oxygen sensors on both sides of the exhaust have very similar readings. When the oxygen sensor is bad, it can cause a false reading and trigger the code.
What does p0430 mean on a catalytic converter?
Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter. P0430 means that the Oxygen sensor downstream of the catalytic converter is registering an improper reading. The upstream and downstream oxygen sensors should show different readings.
What causes the OBDII code on a GMC Yukon?
In the Yukon, OBDII P0430 is often caused by a bad oxygen sensor, but there can be other causes as well. They are outlined directly below. One of the most common trouble codes with all GMC vehicles is the P0430. This code number references a number that is given to you when you plug your GMC Yukon into a OBDII scanner.
How many oxygen sensors does a Yukon have?
Your Yukon has at least two oxygen sensors, one before and after the catalytic converter. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter.

What to do if your catalytic converter code is p0430?
Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases the catalytic convert needs to be replaced to fix the problem. If the P0430 code is combined with other codes, try fixing the other codes first. What does this mean? The cost of diagnosing the P0430 GMC code is 1.0 hour of labor.
