What does a catalytic converter do in a Ford Focus?

Catalytic Converter – A catalytic converter is responsible for scrubbing out as much pollution as possible from the Focus’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.

Why is P0420 catalyst system efficiency below threshold Bank 1?

– Three way catalytic converter Bank 1 does not operate properly. – Three way catalyst converter Bank 1 does not have enough oxygen storage capacity. The Engine Control Module ( ECM) monitors the switching frequency ratio of heated oxygen sensors 1 (front O2 sensor) and heated oxygen sensors 2 (rear O2 sensor).

Why does my Ford Focus not pass emissions?

If your vehicle has the P0420 code, it won’t pass emissions so please be aware of that. The P0420 code in a Ford Focus will often be thrown one of your oxygen sensors are not functioning properly.

What is the trouble code on a Ford Focus?

One of the most common trouble codes with all Ford vehicles is the P0420. This code number references a number that is given to you when you plug your Ford Focus into a OBDII scanner. It doesn’t matter which model you have, this OBDII code has the same meaning for all of them. P0420 is a OBDII trouble code.

What does check engine light mean on catalytic converter?

The check engine light will come on if it’s below this threshold, determined by oxygen sensors that are located before and after the catalytic converter. The sensors will trigger an Onboard Diagnostics (OBD) trouble code that’s stored in your car’s computer. OBD Code P0420 means the catalyst system efficiency is below the threshold.

What are the oxygen sensors on a Ford Focus?

Your Focus 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 causes the P0420 trouble code on a Ford Focus?

There are many things that can cause the P0420 trouble code in your Focus. Here are the most common ones. Oxygen Sensor – The P0420 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.
