The P0302 diagnostic code on your 2022 Lexus IS indicates that cylinder 2 is misfiring beyond acceptable parameters. This sport sedan offers multiple powertrains, each requiring specific diagnostic consideration.
2022 IS Engine Configuration
The 2022 Lexus IS lineup included the IS 300 with either a 2.0L turbo four-cylinder or 3.5L V6 (depending on drive configuration), and the IS 350 with the 3.5L V6. The high-performance IS 500 added a 5.0L V8.
Four-Cylinder Turbo Analysis
The 2.0L turbocharged engine operates under boost pressure. Four cylinders mean each plays a significant role in smooth operation. Boost leaks, ignition component wear, or fuel delivery issues can cause cylinder-specific misfires.
V6 and V8 Considerations
The 3.5L V6 and 5.0L V8 engines use multi-port fuel injection with port injection systems. Cylinder 2 location varies by engine configuration. Both engines are naturally aspirated with traditional diagnostic approaches.
IS 500 V8 Performance
The IS 500's 5.0L V8 produces 472 horsepower. This high-output engine demands quality ignition components. Spark plugs and coils must handle significant thermal stress during spirited driving.
Sport Driving Impact
The IS is often driven enthusiastically. Performance driving accelerates component wear. Ensure maintenance is up to date and address any misfires promptly to prevent engine damage.
