Understanding Renault OBD2 Codes

Renault OBD2 codes follow the standardized format set by the Society of Automotive Engineers (SAE). This format, consisting of a five-character alphanumeric code, ensures consistency across different vehicle makes and models. The first character indicates the system where the fault originates (e.g., “P” for Powertrain, “B” for Body, “C” for Chassis, “U” for Network). The second character further specifies the type of code (e.g., “0” for generic, “1” for manufacturer-specific). The remaining three characters pinpoint the specific fault within the system.

Common Renault OBD2 Codes and Their Meanings

While countless specific codes exist, some appear more frequently in Renault vehicles. For example, P0171 often indicates a lean air-fuel mixture, while P0420 suggests catalytic converter inefficiency.
