Code P0234 (Overboost Error)

Post by Jaye »

I just recently got my Flashpro for my 2019 civic si. Car is stock.
Flashed it with the +6 tune.
Every time Id do a pull the car goes into limp mode and the check engine light, VSA, EPS, brake hold, and some others would come on.
Im running the Hondata Mobile on my nav, and the code P0234 (overboosting problem) would show on it.
Ive tried reflashing the car multiple times already and that would fix the lights but I just run back to the same problem over again.

Anyone else having this issue or can help?

Post your calibration and a datalog using that calibration that shows when this occurs.

Why do you have the secondary O2 sensor disabled?

Oh I must have accidentally disabled it while I was going through the calibration section.

Anything I can do to prevent this error from occurring?

Do you have any throttle pedal modifiers installed?

If you return to stock, form the online menu, do you still get the error?

Hey, I know it’s been a while but I still have this problem. And no, I returned it to stock and don’t get the error anymore. It just keeps happening every time I flash it back tho.
