In older cars, the ignition system for the spark plugs relied on a coil and an electrical contact that, when opened, created the energy needed to generate the high voltage required for the plugs. In parallel with this contact, there is a capacitor that limits the sparking of the contacts to reduce wear.

It can happen that the capacitor shorts out, preventing the spark necessary for the plug. To replace it, remove the cap from the distributor, unscrew the retaining screw of the capacitor wire, and remove it from its seat.

Install a new capacitor by reversing the process. If necessary, clean the points contacts.

How to reset the tyre pressure warning light on the Kia Niro EV?

To reset the tyre pressure warning light on the Kia Niro EV, inflate the tyres until they reach the correct pressure value. This value is indicated on the sticker attached to the driver's door pillar. Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
