Car is choking out and dying. Reads P 0411 code. How do I know if its the motor or just the solenoid valve? How can I check to narrow down what actually is causing the problem? It's on a 2000 VW jetta VR6

• Malfunction Indicator Light (MIL) ON

• Fuel Pump Relay (J17) faulty
• Hoses/Pipes to/between Components faulty/clogged
• Secondary Air Injection Pump (V101) faulty
• Secondary Air Injection Pump Relay (J299) faulty
• Secondary Air Injection Solenoid Valve (N112) faulty

• Check Fuel Pump Relay (J17)
• Check Hoses/Pipes to/between Components
  • Check Secondary Air Injection Hoses/Pipes for Carbonization
• Check Secondary Air Injection Pump (V101)
• Check Secondary Air Injection Pump Relay (J299)
• Check Secondary Air Injection Solenoid Valve (N112)

Find the solenoid valve. Disconnect the hose that goes from it to the air pump. Start engine and feel for air blowing out the hose within the first 10-15 seconds of the engine starting. if there is air blowing the pump is good. If not, suspect the pump or the relay/control circuitry for the pump is bad. If the air is blowing, reconnect the hose and disconnect the hose from the solenoid valve to the exhaust. Start engine again and feel for air blowing out the hose. If no air during the first 10-15 seconds suspect a bad solenoid valve or control circuitry for the valve. My Ford Focus had a bad valve and this was how I determined the problem.
