Procédure de réapprentissage papillon ou pédale non effectuée

A throttle body or pedal assembly that has been cleaned, disturbed or replaced without the module being taught its new mechanical limits. The part is fine and the fitting is fine; what is missing is the step that tells the module where the stops now are — and until it is done, the module compares live readings against limits belonging to the old assembly.

It produces genuine codes about a healthy system, which is what makes it worth naming. Minimum and maximum stop performance codes are the module observing that the sensor's endpoints no longer sit where it learned them. A cleaned throttle body is the commonest trigger, because removing carbon changes exactly the closed position the module had adapted to over years.

Two practical points. Clearing the codes is not the procedure — the learned values persist, so the codes return within a few drive cycles and the fault looks intermittent. And the procedure is specific: some vehicles relearn automatically over a defined key and idle cycle, others require a scan tool to command it, and doing the wrong one leaves the adaptation untouched. Look it up for the vehicle rather than assuming the ignition-cycle ritual works; it does on some and does nothing at all on others.
