What Does P0430 Mean on Your 2024 Volkswagen Taos?
A P0430 code on your 2024 Volkswagen Taos means the catalytic converter on bank 2 is not meeting emissions efficiency requirements. The 2024 Taos continues with the 1.5L turbocharged four-cylinder EA211 Evo engine, now producing 158 horsepower and 184 lb-ft of torque. The exhaust system uses catalytic converters monitored by upstream and downstream O2 sensors.
On a brand-new 2024 model, this code is unusual. The ECU compares O2 sensor data on bank 2 to evaluate converter health. When the downstream sensor shows patterns indicating reduced efficiency, the P0430 is stored.
Symptoms You Might Notice
- Check engine light illuminated
- Minor fuel economy decrease
- Faint sulfur smell from exhaust
- Slight hesitation
- Emissions test failure
Common Causes of P0430 on the 2024 Volkswagen Taos
- Defective O2 sensor — A sensor manufacturing defect is the leading suspect on a new vehicle.
- ECU software issue — Software calibration refinements may be needed for the emissions monitoring system.
- Catalytic converter defect — Rare but possible. Fully warranty-covered.
