ŚredniSecondary Air Injection (AIR) System – Bank 1 – Air Pump Circuit Malfunction.
Fault code P1415 indicates a problem with the secondary air injection (AIR) system on engine bank 1. This system pumps fresh air into the exhaust manifold during cold starts to help heat the catalytic converter faster and reduce emissions. The most common causes are a faulty air pump, blown fuse, faulty wiring, or a blocked check valve – further diagnosis requires specialized equipment and technical knowledge.
Symptoms
Check Engine light is on; during cold start, the engine may run rough or have reduced power; possible worsening of emission test results; in some cases, a smell of unburned fuel from a cold engine.
Possible causes
Faulty or blocked secondary air pump. Blown AIR pump fuse. Faulty wiring or corroded connectors at the pump or relay. Faulty air pump relay. Leaking, cracked, or disconnected vacuum/pressure hoses in the AIR system. Contaminated or blocked check valve in the air injection system.
