OBD2 Diagnostic Trouble Code P0430 means that the sensor in the catalytic converter located in bank 2 has detected the catalytic converter’s efficiency below the threshold. A catalytic converter’s job is to burn up the remaining raw fuel after the combustion process and to eliminate or reduce harmful emissions.
A P0430 code indicates the catalyst efficiency has fallen off. If there are no other codes indicating misfires and if the check engine light is not blinking, you should be OK to drive your car.
Can a bad O2 sensor cause a P0430 code?
A faulty catalytic converter is the most frequent cause of a P0430 trouble code. Common issues that can cause this OBD-II code include: Faulty catalytic converter. Damaged or failing O2 sensor that gets incorrect readings of emission levels.
Code P0430 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.

How do I fix Bank 2 P0430?
You’ll need to successfully diagnose the cause, and the only way to fix the P0430 fault to show up again is by replacing the faulty parts or fixing the leak in the exhaust. If there’s a leak in the exhaust system, the code can be fixed by plugging the leak.
What causes a lean condition on bank 1 and bank 2?
If you have codes stored in the engine computer for lean bank 1 and 2 is caused by the entire engine is running lean. This is caused by not enough fuel getting into the engine or too much unmetered air getting into the engine and the computer cannot compensate anymore to run it normal.
What is Bank 1 on a catalytic converter?
Bank 1 refers to the side of the engine that houses the number one cylinder. The opposite side of the engine is Bank 2.
How much does it cost to fix P0430?
How much will it cost to fix? Running a diagnostic for the P0430 will cost between $75 to $150 and take around an hour of labor. The cost of repairs can vary depending on what needs to be replaced, but the total cost of parts and labor can total anywhere from $100 to $2,400.

Is Bank 1 Bank 2 or P0420?
Simply put, a P0420 code means that the catalyst system efficiency of your car is below threshold (Bank 1). The P0420 error number indicates a low catalyst system efficiency. This is usually caused by issues with your vehicle’s exhaust or fuel systems.
Is P0420 same as P0430?
P0420 and P0430 both showed up and are both DTCs associated with the left and right catalytic converter banks. These codes relate to Catalyst system efficiency that is below the threshold. In each case, the code indicates where the problem is located that triggers it.
The most common cause of a P0420 code is a faulty catalytic converter.
Why am I still getting a P0420 code after I replaced my catalytic converter?
The code P0420 can be caused by the catalyst, O2 sensors before and after the catalyst. If both O2 sensors and catalyst was replaced then you may have an exhaust leak at the manifold or pipes.
Will catalytic converter cleaner fix P0420?
What can cause a false catalytic converter code?
Worn or internally failing catalytic converter (Most Common)
Faulty oxygen sensor.
Faulty air-fuel sensor.
A leak in the exhaust system.
Misfire (the root cause of converter failure)
Rich or Lean air-fuel ratio (the root cause of converter failure)
Leaded Gasoline (the root cause of converter failure)
Can a cracked exhaust manifold cause a P0420 code?
The performance is measured by the rear oxygen sensor. If the exhaust manifold is allowing air to enter the exhaust system, that excess air can mess with the measurements made by the oxygen sensor. So to answer your question directly, yes, it is possible than a manifold leak could cause a false code P0420.
