What exactly is code P0420?

The definition of the OBD-II P0420 code is ” Catalyst System Efficiency Below Threshold (Bank 1) “. When the ECU stores this code, it means that the catalytic converter is not operating at maximum efficiency and may need replacement. Car fault code: P0420

What causes code P0420?

The code P0420 can be caused by an engine problem that’s pouring too much fuel into the catalytic converter, excess fuel that the PCM can’t control, a vacuum leak that’s causing excess air to enter the catalytic converter, OR, a damaged catalytic converter.

What is triggering my P0420 code?

P0420 is triggered in the engine control module when there is a problem with the efficiency of the catalytic converter . The engine control unit uses two O2 sensors, one in the front of and one behind the catalytic converter to measure the efficiency of the catalytic converter.

Is it important to fix code P0420?

Repairing error code p0420 is generally inexpensive, so there’s no major cause for concern if it appears. The P0420 diagnostic trouble code is known as a generic fault code. It is set when the Onboard Diagnostic II or OBD II catalyst monitor can sense a drop in its converter efficiency.

What causes the P0420 trouble code on a Honda Civic?

There are many things that can cause the P0420 trouble code in your Civic. 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.

What is the trouble code on a Honda Civic?

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

Why is a P0420 trouble code never a bad oxygen sensor?

NOTE: This is why a P0420 trouble code is almost never a bad oxygen sensor — because the ECM has already tested the downstream sensor. If it isn’t responding properly, it will set a trouble code. The same applies to the upstream sensor.

What does P0420 mean on a catalytic converter?

Here’s the official definition of a P0420 trouble code: P0420 Catalyst System Efficiency Below Threshold (Bank 1). What the code is telling you is that the catalytic converter has failed an efficiency test. In 99.5% of the cases, this code means that the catalytic converter itself is bad and must be replaced.

What to do if your O2 sensor is not working?

Once you verify from the o2 sensors that the catalytic converter isn’t functioning efficiently, I show you how to modify the downstream sensor #2 mounted on or after the catalytic converter with a simple Resistor Capacitor (RC) low-pass filter to smooth out the signal by removing “high frequency” (faster than 5 seconds) changes in the o2 levels .

What does the P0420 code on a check engine light mean?

When check engine lights are scanned, a p0420 code is a very common result. It’s actually a generic code, meaning it can be thrown from any vehicle after 1996. Commonly, people think the p0420 code indicates that the oxygen sensors need to be replaced, but that’s definitely not always the case.

What causes OBDII P0420 on Honda CRV?

It covers Honda CR-V P0420 meaning, symptoms, causes, and possible solutions. In the CR-V, 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’s the problem with my Honda Accord P0420?

It covers Honda Accord P0420 meaning, symptoms, causes, and possible solutions. In the Accord, 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 oxygen sensor to read lean?

If the upstream and downstream oxygens sensors are both switching from rich to lean, that’s the sign of a dead catalytic converter. An exhaust system leak really screws up the P0420 testing routing. An exhaust leak near the upstream sensor can cause the downstream sensor to read a steady lean condition.
