A P0302 code on your 2022 Lexus ES indicates that the engine control module has detected cylinder 2 misfires beyond acceptable parameters. This luxury sedan demands proper diagnosis to maintain its smooth, refined driving experience.
2022 ES Powertrain Options
The 2022 Lexus ES offered two powertrain choices: the ES 350 with a 3.5L V6, and the ES 300h hybrid with a 2.5L four-cylinder paired with electric motors. Each engine type requires specific diagnostic considerations.
ES 350 V6 Analysis
The 3.5L V6 features Toyota's D-4S dual injection system combining direct and port injection. This design helps prevent the carbon buildup common in direct injection-only engines. Cylinder 2 is located on the front bank for easier access.
ES 300h Hybrid Configuration
The hybrid variant uses a 2.5L four-cylinder engine working with electric motors. With only four cylinders, each one significantly affects smooth operation. The hybrid system may partially mask misfire symptoms during electric-assisted driving.
Luxury Vehicle Standards
The ES is Lexus's flagship sedan known for exceptional comfort and refinement. Any misfire disrupts this experience noticeably. Prompt diagnosis and repair restore the smooth operation expected of this luxury vehicle.
Diagnostic Approach
Identify your specific model (ES 350 or ES 300h) before beginning diagnosis. The V6 and four-cylinder engines have different specifications and potential issues. Lexus dealer diagnosis ensures proper procedures are followed.
