What is the P0420 Code?

The P0420 code is a diagnostic trouble code (DTC) that indicates a problem with the catalytic converter's efficiency.

This code is common across various vehicle makes and models, including the Jeep Renegade Limited.

Common Causes of P0420 Code

There are several reasons why your Jeep Renegade Limited may trigger the P0420 code. Here are some of the most common causes:

1. Faulty Catalytic Converter: The most common reason for a P0420 code is a malfunctioning catalytic converter. This can occur due to age, damage, or contamination.

2. Oxygen Sensor Issues: The upstream or downstream oxygen sensors may be faulty or malfunctioning, leading to incorrect readings and triggering the P0420 code.

3. Exhaust Leaks: Any leaks in the exhaust system can affect the performance of the catalytic converter and lead to the P0420 code.

4. Fuel System Problems: Issues with the fuel system, such as a rich or lean fuel mixture, can also cause the catalytic converter to fail.

5. Engine Misfires: If the engine is misfiring, it can lead to unburned fuel entering the catalytic converter, causing it to overheat and fail.
