A P0303 code on your 2022 Toyota Tundra indicates that the engine control module has detected cylinder 3 misfires beyond acceptable parameters. The completely redesigned Tundra features an all-new powertrain.
2022 Tundra: Complete Redesign
The 2022 Toyota Tundra debuted an all-new generation with a 3.5L twin-turbocharged V6 replacing the previous V8. The i-FORCE MAX hybrid variant adds electric assistance.
3.5L Twin-Turbo V6
The new V6 produces 389 horsepower (437 hp in hybrid form) through twin turbochargers. In this V6, cylinder 3 is on one bank. Bank-specific issues should be considered.
Twin-Turbo Technology
Two turbochargers pressurize intake air for impressive power. Boost system integrity is critical for proper combustion across all cylinders. Check both turbo systems during diagnosis.
i-FORCE MAX Hybrid
The hybrid variant adds electric motor assistance. Misfires affect the combustion engine specifically, though electric power supplements overall output.
New Platform Reliability
The all-new platform and powertrain represent significant engineering. Early reliability data is developing. Most issues are covered under warranty.
