What is the P0306 Code?

The P0306 code is a diagnostic trouble code (DTC) that indicates a misfire in cylinder 6 of your engine. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors the performance of your vehicle's engine and emissions system.

Key Points:

  • P0306: Indicates a misfire in cylinder 6.
  • Part of OBD-II: Monitors engine performance and emissions.

Common Causes of P0306 Code

There are several reasons why you might see the P0306 code in your Lexus ES 300h. Here are some of the most common causes:

  1. Faulty Spark Plug: A worn or damaged spark plug can lead to incomplete combustion, causing a misfire.
  2. Ignition Coil Issues: A malfunctioning ignition coil can prevent the spark plug from firing properly.
