A P0302 code on your 2022 Buick Envision indicates that the engine control module has detected cylinder 2 misfires beyond acceptable parameters. This compact luxury crossover features a turbocharged four-cylinder engine.
2022 Envision Powertrain
The 2022 Buick Envision is powered by a 2.0L turbocharged four-cylinder engine producing 228 horsepower. This efficient powerplant combines turbocharging with direct injection for refined performance.
Four-Cylinder Dynamics
With four cylinders, each contributes 25% of power output. Cylinder 2 misfires significantly affect smooth operation. Rough idle, vibration, and reduced power are immediately noticeable.
Turbocharger Function
The turbocharger increases engine output by pressurizing intake air. Boost system integrity is essential for proper combustion. Leaks can create lean conditions affecting individual cylinders.
Direct Injection Considerations
Direct fuel injection delivers fuel at high pressure into the combustion chamber. While efficient, this design can contribute to carbon buildup on intake valves over time.
