Will O2 sensors work without a catalytic converter?
The in-cat or after-cat O2 sensors are just used to check the efficiency of the cat itself. Therefore, in most modern vehicles a car can run just fine without a cat.
What causes an odyssey to throw a P0420 code?
Odyssey Timing – If your Odyssey is misfiring or the exhaust timing is off, this can affect the gasses that are actually going to the O2 sensors enough to cause the P0420 code to register. Exhaust Leak – If there’s a noticeable exhaust leak coming from the vehicle it can change what the O2 sensors register enough to throw the P0420 code.
What does OBDII trouble code mean on Honda Odyssey?
P0420 is a OBDII trouble code. The code technically stands for: Your Odyssey 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 O2 sensor to show the code po420?
Rich or lean mixtures can damage the catalytic converter, and when the catalytic converter is damaged/filled with fuel, the efficiency will be low, and the rear O2 sensor will see that and show the trigger the code Po420.
Why does my Honda Odyssey 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 Honda Odyssey will often be thrown one of your oxygen sensors are not functioning properly. Typically, the code will be triggered by the upstream oxygen sensor (before the converter).
What is the problem with the Honda Odyssey P0420?
It covers Honda Odyssey P0420 meaning, symptoms, causes, and possible solutions. In the Odyssey, OBDII P0420 is often caused by a bad oxygen sensor, but there can be other causes as well. One of the most common trouble codes with all Honda vehicles is the P0420.

What causes the P0420 code to be thrown?
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.
