What Does P0430 Mean on Your 2024 Ram 1500?
A P0430 code on your 2024 Ram 1500 indicates the catalytic converter on bank 2 is not meeting its emissions efficiency threshold. The 2024 Ram 1500 offers several engine options: a 3.6L Pentastar V6 (305 hp), a 5.7L HEMI V8 (395 hp) with eTorque mild-hybrid, and a 3.0L Hurricane twin-turbo inline-six (420 hp). All these engines use dual catalytic converters, and P0430 targets the bank 2 side.
On a new 2024 model, this code is unexpected. The PCM compares upstream and downstream oxygen sensor data on bank 2 to assess converter health. When the downstream sensor indicates reduced efficiency, the code is stored.
Symptoms You Might Notice
- Check engine light on the dashboard
- Decreased fuel economy (noticeable on a truck)
- Rotten egg smell from the exhaust
- Possible MDS (Multi-Displacement System) deactivation issues on HEMI
- Emissions test failure
Common Causes of P0430 on the 2024 Ram 1500
- Faulty O2 sensor — A defective downstream sensor is the most likely cause on a new truck.
- ECU software issue — New model calibrations may need updating, especially with the new Hurricane engine.
- Catalytic converter manufacturing defect — Rare but possible. Fully covered by Ram's warranty.
- Exhaust system assembly issue — Minor gasket or connection imperfection.
