Decoding the Secrets: Understanding Honda OBD2 Codes
OBD2, or On-Board Diagnostics II, is a standardized system used in vehicles to diagnose malfunctions. When your Honda’s check engine light illuminates, it means the OBD2 system has detected a problem and stored a corresponding code. These codes, often referred to as Diagnostic Trouble Codes (DTCs), are the key to understanding what’s happening under the hood.

How to Read a Honda OBD2 Code
Each code follows a specific structure. The first letter, “P,” indicates a powertrain-related code. The next character is a “0” for generic codes or a manufacturer-specific number (e.g., “1” for Honda). The following two digits indicate the system (e.g., “42” for emissions). The final two digits specify the exact problem. For a complete list of Honda-specific codes, see our honda code list obd2 page.
What Does P0442 Mean on a Honda?
