About Air Metering Codes
This page lists all 484 OBD-II diagnostic trouble codes classified under the Air Metering category. These codes are stored by your vehicle's onboard computer when a sensor detects a malfunction in the air metering system. Each code begins with a letter indicating the system (P for Powertrain, B for Body, C for Chassis, U for Network) followed by four digits that identify the specific fault.
When your check engine light comes on, an OBD-II scanner reads these stored codes to help pinpoint the problem. Generic codes (where the second digit is 0) follow the SAE J2012 standard and mean the same thing on every vehicle. Manufacturer-specific codes (where the second digit is 1) may have different meanings depending on the vehicle brand.
