My 2000 Mustang6cylcheck engine light came on and I checked the codes and got: P1414-Manufacturer Control Auxilary Emmissions Controls and P0411-Secondary Air Injection System Incorrect Flow. Anysolutions to these codes?Thanks in advance.

 

P0411 refers to DTC P1411..

The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system

Check for..

Electric AIR Pump
Hose from AIR pump leak
AIR bypass solenoid leak/blocked
Hose from AIR pump blocked
AIR bypass solenoid stuck open/closed

P1414

The secondary air injection system monitor circuit is high, indicating the electrical AIR pump is on although the electrical AIR pump was commanded off by the PCM.

Open AIR monitor circuit from the pump
AIR circuit short to power
Damaged solid state relay
Open AIR pump ground
Damaged AIR pump
Damaged PCM

 

Thanks for the quick response Hayapower. I will report back after I check out your recommendations.
