plz help me , solve my problem

[kyeongho]

hi , i am mustang gen 7, gt convertible owner in korea.
i just watched corsa exhaust extrem cat0back, and i set it up yesterday.

but i got engine light and error code P26FE
the exhaust valve continues to open and close repeatedly, and the vehicle experiences an error in the exhaust setting. Also, an engine warning comes in.

The installation company said that if the vehicle learns exhaust over time, the error will disappear, but I don't think so.

so i what to know reason why i got this problem, and i want to slove my problem


Please help me if you have a similar experience to me

I had the exact same thing happen to me when I had a Flowmaster Outlaw Active exhaust installed. Took it back, and they found one of the actuator mounts was loose and it wasn't able to engage/sense the position of the valve. There was no learning curve for mine once it was tightened up/fixed.

Corsa has a design flaw in their earlier generations of the exhaust that cause the valves to stick. They offer a service kit that fixes it (a screw and spring that you replace on each valve). If you contact their warranty support, they will be able to tell you if your exhaust is impacted. I really recommend you email them AND then follow up with a call a few times until you speak to a person.

This is an issue that tends to clear after the exhaust heats up, so I suggest you see if your dash DTC clears after driving around a few minutes. The S550 will try to reset the valves and clear the code every 60 seconds or so; the s650 is probably similar.

If you drop your exhaust, you can identify this stuck-valve issue because you won't be able to easily hand-turn the valves w/ the actuators off.

Also -- it's been a while -- but there is a service procedure for the exhaust re-learn in ForSCAN for the S550. I have a GT350, so I don't happen to know if ForSCAN supports MY2024+, but you can try to install ForSCAN and run that service procedure.

If you don't have access to ForSCAN, you can try this in-car exhaust relearn procedure for an S550, which might be similiar in your vehicle. Some users mentioned it helped, so perhaps it works for you.
