A P0411 code means: Secondary Air Injection System upstream flow. The air pump supplies oxygen to the exhaust manfolds during the first few minutes after the car is started. The PCM controls the EAM relay which controls the EAM air pump. Check: The 30 amp fuse label "Thermactor Pump Fuse." Voltage to the air pump should be battery voltage. The air hoses on the air pump for damage or blockage. Check the vacuum hoses to the one or two vacuum controled air diverter valves. PCM controled vaccum switch for deverter values.
