Code P2430 Description

The P2430 diagnostic trouble code (DTC) indicates a problem with the Secondary Air Injection System Air Flow/Pressure Sensor Circuit Bank 1. This system is responsible for reducing harmful emissions by injecting fresh air into the exhaust system to help burn any remaining fuel vapors before they are released into the atmosphere. The air flow/pressure sensor in this system measures the flow rate and pressure of the air being injected, allowing the engine control module (ECM) to adjust the system's operation as needed.
