P1476 Chrysler Code - Too Little Secondary Air Injected
Quick Answer
The P1476 Chrysler diagnostic trouble code indicates that there is too little secondary air injected into the vehicle's emissions system. Common causes include Clogged Hoses: Accumulated debris or dirt can clog the hoses responsible for delivering secondary air into the exhaust system, Faulty Pump: A malfunctioning secondary air injection pump may fail to deliver the correct amount of air into the system, Stuck Diverter Valve: A stuck diverter valve can prevent the proper flow of secondary air, leading to insufficient injection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
