A P0420 diagnostic code on your 2022 Toyota Tundra indicates that Bank 1's catalytic converter efficiency has dropped below acceptable levels. The completely redesigned 2022 Tundra features a new twin-turbo V6 engine.
2022 Tundra Engine Options
- 3.4L Twin-Turbo V6 (i-FORCE): 389 hp
- 3.4L Twin-Turbo V6 Hybrid (i-FORCE MAX): 437 hp combined
Both variants use the same V6 base engine with dual exhaust banks. P0420 affects Bank 1 specifically.
P0420 on Newer Vehicle
A 2022 Tundra showing P0420 is relatively early for converter failure:
- O2 Sensor Issues: More likely than converter failure
- New Platform: May have software calibration needs
- Truck Use: Heavy towing can accelerate wear
Warranty Coverage
A 2022 Tundra should be under emissions warranty.
