I have a mazda 5 2,0 143hp. I got it with flashing dfp light. The dfp was then cut out of the exhuast, the exhaust was mounted and the 2 pipes for the dfp sensor was connected.

Next an ecu mapping with dfp removed was uploaded to the ecu.

At first fire up all the lights went out, and i went for a drive. The car was fine, no longer in limp mode but after 200meters the dfp light came back, flashing, and the engine went into limp mode again.

I attached a dianostisk to clear errors, but there are no errors.

Can anyone help with what i am doing wrong. I have attempted force reset of dfp, via the cable in from to minus on battery, pump gas 10 times, but nothing works.

Help, thank you.
