What Does P0430 Mean on Your 2022 Nissan Rogue?
Your 2022 Nissan Rogue has triggered a P0430 code, meaning the catalytic converter on Bank 2 isn't converting exhaust pollutants efficiently enough. The 2022 Rogue uses Nissan's innovative 1.5L variable-compression turbocharged 3-cylinder engine (KR15DDT). On this inline engine, Bank 2 refers to the secondary catalyst or downstream monitoring position in the exhaust system.
At 2-4 years old, the 2022 Rogue shouldn't have a worn-out converter. Sensor, software, or minor exhaust issues are the most likely culprits.
Symptoms You May Notice
- Check engine light on
- Mild fuel economy decrease
- Possible sulfur smell from exhaust
- Slight hesitation during acceleration
- Emissions test failure
Common Causes of P0430 on the 2022 Rogue
- Faulty downstream O2 sensor — A malfunctioning rear oxygen sensor is one of the most probable causes on a newer vehicle.
- ECM software calibration — The variable-compression engine may benefit from an updated ECM calibration that refines catalyst monitoring.
- Exhaust leak — Even on newer vehicles, a connection or gasket issue can create a leak affecting sensor accuracy.
- Catalytic converter defect — Manufacturing defects are uncommon but possible.
How to Diagnose the Problem
