  • Second Character: Specifies whether the code is generic (0) or manufacturer-specific (1).
  • Third Character: Denotes the subsystem (e.g., fuel system, ignition system).
  • Fourth and Fifth Characters: Indicate the specific fault.

• Common OBD2 Codes and Their Meanings:

  • P0300: Random/Multiple Cylinder Misfire Detected.
  • P0171: System Too Lean (Bank 1).
  • P0420: Catalyst System Efficiency Below Threshold (Bank 1).
  • P0101: Mass Air Flow (MAF) Sensor Circuit Range/Performance.
  • P0301: Cylinder 1 Misfire Detected.

Example: Interpreting P0300

• P: Powertrain
• 0: Generic code
• 3: Ignition system
• 00: Random/multiple cylinder misfire

This code suggests that there is a misfire occurring in multiple cylinders or a random misfire that the system cannot attribute to a specific cylinder.

According to research from AAA, misfires can lead to decreased fuel efficiency and potential engine damage if left unaddressed.
