2011 Ford Fiesta SE Check Engine Light: OBD Code ER0412 Explained - Safe to Drive?

Model: 2011 Ford Fiesta SE Fault Code: P0412 Posted: 2014-07-19 12:14

Hi everyone, My 2011 Ford Fiesta SE has triggered the check engine light, and I've managed to access the OBD-II diagnostic menu. The system displays 'ER0412', which I understand corresponds to a Secondary Air Injection System fault — related to emissions control. I'm relatively new to car maintenance, so I'd like clarification on what this means in practical terms. Is it safe to drive my vehicle until the end of extended warranty (on the 29th)? I need to make two trips out of town before then and am concerned about potential performance or safety issues. Additionally, why does my OBD menu show 'ER' instead of the more common 'P' prefix used in other vehicles? Is this a model-specific issue or a difference in diagnostic system versions? Thanks for any insights! -Matt

You mentioned you accessed the OBD menu — could you clarify how exactly you did that? This might help others understand the process, especially since 'ER' codes are less common than 'P' codes. Is this a known variation in Ford Fiesta SE systems?

I had to hold in the button on my dash while I turned the car on (without ignition). It came up gage, the showed all the lights possible on the screen, then all the lcd possible on the dash, amd then that code, which I think is a dtc code? Sorry, I am really new to this. Is that not the code I am looking for?
