Understanding OBD2 Codes
OBD2 codes are alphanumeric representations of issues detected by the vehicle's onboard computer. The codes are divided into two main categories: generic and manufacturer-specific.
Generic Codes
These codes are standardized across all vehicles and begin with a letter followed by four digits (e.g., P0123). Common generic codes include:
- P0300: Random/Multiple Cylinder Misfire Detected
- P0420: Catalyst System Efficiency Below Threshold
- P0171: System Too Lean (Bank 1)
Manufacturer-Specific Codes
These codes are unique to specific manufacturers and may vary in format. They often provide more detailed information tailored to the vehicle's systems.
