So to get rid of P0420 without replacing the cat you have to inhibit the sensor’s ability to measure oxygen or modify the data the computer receives to look normal. I think poisoning the sensor has a similar effect to the non-fouler trick. Just cleaning the sensor is the opposite of what you want to do, and probably achieves nothing.

What is triggering my P0420 code? Let’s take a look at some of the things that you can do to diagnose the problem:
- Performing a visual check of the muffler, catalytic converter and exhaust pipes for any damage is the easiest place to start.
- Visually inspect the upstream and downstream o2 sensors for any loose connections or disconnected wires.
- Check to see if there are other codes paired along with the P0420.
What does code P0420 mean? What are the symptoms of code P0420?
- Stored trouble code, and an illuminated warning light
- Depending on the root cause of code P0420, other codes relating to misfires, fuel pressure, engine temperature, oxygen or air/fuel ratio sensors, and others may be present
- Vehicle may not pass an emissions test
What could a P0420 code mean? Steps to diagnose the P0420 error code:
- A simple way to check if the problem is in the catalytic converter.
- Disconnect one of the oxygen sensors located before and behind it.
- If there aren’t any misfires but the Check Engine Light remains on, it is likely not going to be a defective oxygen sensor or wiring issue with it.
- You may have a bad catalytic converter or other engine components.

How serious is a P0420 code? The P0420 code itself is not causing any serious damages to your vehicle for short distances. However, driving long distances and ignoring the trouble code is not recommended. Fix it as soon as possible.
What can cause a P0420 code? The root cause of the p0420 code can vary, depending upon the vehicle and situation at hand. A faulty catalytic converter is one common cause of a p0420 code, though exhaust leaks, misfires, or a defective oxygen sensor are also a suspect.

Is it important to fix code P0420? The P0420 code is a DTC that indicates your car’s catalyst converter is experiencing an issue. This error needs to be fixed as early as possible because the catalyst system in modern vehicles plays an important role. What Does the P0420 Code Mean? How Serious is the P0420 Code? 1. Engine Misfires 2. Check Engine Light is Illuminated 3.

What causes a P0420 code?
- What does code P0420 mean on my car?
- Severity rating of the code: MODERATE severity: if you drive for a long time with this code on, you may cause damage to the engine of the vehicle.
- Causes of Code P0420: The most likely cause of code P0420 is that you have a faulty catalytic converter, but it may also be due to other causes, it may
