2002 Ford Mustang P0411 Code: Causes and Fixes for Secondary Air Injection System

Model: 2002 Mustang Fault Code: P0411 Posted: 2006-01-20 15:46

I've been informed that the P0411 diagnostic trouble code indicates an issue with either the secondary air injection valve or its control module. Does anyone have hands-on experience troubleshooting this code on a 2002 Ford Mustang? What are the most effective solutions? Thanks, Wes

I've been dealing with the P0411 code for years on my 1998 Cobra. The code would appear every two weeks. After researching online, I tried replacing the DPFE (Differential Pressure Feedback) sensor, which resolved the issue for three weeks. However, after driving through a puddle, the code returned. I'm now back to troubleshooting. I plan to replace the sensor again and monitor if the problem persists. The cost was $115.
