What does the OBDII code mean on a Honda CRV?
Honda CR-V P0420 OBDII Code Defined. P0420 is a OBDII trouble code. The code technically stands for: Catalyst System Efficiency Below Threshold. Your CR-V has at least two oxygen sensors, one before and after the catalytic 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.

What does it mean when your engine code is po420?
This warning comes in an engine trouble code – PO420 or PO421. Depending on the symptoms, there are a few likely causes and solutions. For many drivers, the first sign that the catalyst efficiency is below the threshold is that the Check Engine Light turns on. In many cases, drivability will appear quite normal.
Can a damaged catalytic converter trigger the code po420?
Yes, they can, but not in the way you think. 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.
What does it mean when a car has a po420 code?
When your vehicle generates those emission codes it simply means that the converter is not able to function properly. Remember that the catalytic converter is at the very end of the emission diagnostic system, and a number of things can go wrong upstream of the converter that can cause. a PO420 (or PO430) MIL light illumination.
Yes, they can, but not in the way you think. 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.
What does p0430 mean on Honda catalyst system?
P0430 HONDA Tech Notes As the code description implies the P0430 code means that the vehicle’s control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting).
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 do you need to know about po420 or po430?
PO420 or PO430 CODE CATALYTIC CONVERTER FAILURE DIAGNOSTICS Following is a list of procedures that should be accomplished before the final determination that a new catalytic converter is needed. These are known as diagnostic procedures and go far beyond someone just performing a simple code reading and then declaring a bad converter is present.
P0430 HONDA Tech Notes As the code description implies the P0430 code means that the vehicle’s control module has detected that the three-way catalytic converter is not working properly (is not as efficient as the factory is expecting).
What does it mean if your check engine light says po420?
It is important to remember that if your “Check Engine Light” illuminates and someone just simply reads a code of PO420, 421, 430 or 431 this does not necessarily mean the Catalytic Converter is bad! All that code says is either Converter operating below efficency or Converter operating below threshold.
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 CR-V 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.
Why is my Honda CRV not passing emissions?
The software in your vehicle believes that the catalytic converter is no longer doing its job. If your vehicle has the P0420 code, it won’t pass emissions so please be aware of that. The P0420 code in a Honda CR-V will often be thrown one of your oxygen sensors are not functioning properly.
Why does my Honda CRV groan when I turn?
RepairPal received 170 reports about Honda CR-V vehicles that groaned each time the driver made a turn. The cause of the groaning was the differential fluid breaking down. In those cases, a quick flush and some replacement fluids solved the problem.

Why is the lock on my Honda CRV not working?
Locks that aren’t working properly make it impossible to secure your vehicle. In the case of the Honda CR-V, the bulk of the locking complaints filed involve locks that got stuck in the lock position, forcing drivers to find creative ways to enter their vehicle.
Where does the P0420 trouble code come from?
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.
What does the service code P0420 mean?
P0420 is a trouble code that gets stored in your car engine’s control unit when it recognizes a problem with the catalytic converter’s efficiency . There are many different reasons for this, so you need to know how to diagnose this trouble code properly.
What does a computer code P0420 mean?
P0420 code is associated with catalytic converters. Catalytic converters break down the harmful pollutants generated during the combustion cycle. The converter is fitted with gold and platinum mesh to filter the exhaust fumes.
What does the engine error code P0420 mean?
A P0420 Code means that the engine control unit recognizes that the catalytic converter’s efficiency is below the threshold. The ECM uses two O2 sensors, one in the front and one in the back of the catalytic converter, to measure the efficiency. If the efficiency is low, the P0420 code will be triggered. In most cases, a P0420 code is caused by a bad catalytic converter .
