How to Manage the Engine Management Light on a Ford Focus

Model: Ford C Max MK 2 - Years 2010-2019
Part: Warning light – error code

What to do when the engine light comes on in a Ford Focus: one thing not to do is reset the light without doing anything or ignore it: the light comes on when the ECU records a fault code: to know what triggered it, we need to read this code. Therefore, it is necessary to get an OBD2 diagnostic reader, like the one we can find on Amazon with code B0FLVH6W7J priced at £31.99, with free delivery. These devices connect to the socket under the dashboard and are used with an app on your phone: we will obtain a code and act according to the code and the behaviour of the car. Steady red light + loss of power = serious fault active. We must stop and call a tow truck. Steady yellow light and no symptoms = often a minor fault: drive cautiously and schedule the repair. Flashing yellow light = serious fault in progress: unburnt fuel is damaging the catalyst. We must stop immediately and call the tow truck. Repair the fault and reset the light with our OBD2 scanner.
