A P0302 code on your 2022 Acura MDX indicates that the powertrain control module has detected cylinder 2 misfires beyond acceptable parameters. The redesigned MDX features advanced powertrains requiring specific diagnostic approaches.
2022 MDX Powertrain Options
The redesigned 2022 Acura MDX offered two engines: a 3.5L naturally aspirated V6 in standard models and a 3.0L turbocharged V6 in the performance-focused Type S. Each engine has different diagnostic considerations.
3.5L V6 Standard Engine
The naturally aspirated 3.5L V6 features Honda's i-VTEC variable valve timing and direct injection. This proven engine design is generally reliable. Cylinder 2 is located on the rear bank, requiring some component removal for full access.
3.0L Turbo V6 Type S
The Type S variant features a 3.0L twin-turbocharged V6 producing 355 horsepower. The turbochargers add complexity—boost leaks or wastegate issues can affect cylinder-specific combustion. High power output demands robust ignition components.
Direct Injection Effects
Both engines use direct fuel injection, which can contribute to carbon buildup on intake valves over time. This buildup affects airflow and can cause misfires. Higher-mileage vehicles are more susceptible.
Acura Quality Standards
Acura maintains high quality standards as Honda's luxury division. Most misfire issues are isolated component failures rather than design problems. Proper diagnosis identifies the specific cause.
