That nagging yellow tyre pressure warning light in your Ford Focus can be both annoying and inconvenient. But fear not, fellow Focus fanatic! This guide will help you diagnose the issue, fix it fast, and get back on the road with confidence.
First things first
Take a deep breath. A lit tyre pressure warning light doesn’t necessarily mean doom and gloom. Often, it’s simply a reminder to check your tyre pressure, which can fluctuate due to temperature changes or slow leaks.
Step 1:
Check the Pressure. Grab your trusty tyre pressure gauge (or head to a gas station) and check the pressure in all four tyres, including the spare.
Compare the readings to the recommended pressure for your Focus model, found on a sticker inside the driver’s door jamb or in the owner’s manual. Remember: cold tyres typically need slightly more air than warm ones.
Step 2:
Inflate if Needed. If any tyre is underinflated, simply fill it up to the recommended pressure using a pump. Don’t go overboard, though! Overinflation can be just as dangerous as underinflation.
Step 3:
Reset the Light. Once all tires are at the correct pressure, you’ll need to reset the warning light. The process varies depending on your Focus model year.
Here are some general steps:
- For models before 2015: Turn on the ignition but don’t start the engine. Press and hold the “OK” button on the steering wheel until the tyre pressure warning light flashes. It will then turn off, indicating the system has been reset.
- For models 2015 and later: Use the buttons on the steering wheel and the information display to navigate to the “Tyre Pressure Monitoring System” menu. Select “Store Pressures” and hold the “OK” button until the system confirms pressure has been stored.
Step 4
Monitor the Light. Go for a short drive and see if the warning light reappears. If it does, there might be a more serious issue, like a slow leak or a faulty sensor.

Further Troubleshooting
- Persistent light: If the light remains on even after proper inflation and resetting, your Focus might have a faulty sensor or leak. Consult your owner’s manual or a qualified mechanic for further diagnosis and repair.
- Rapidly deflating tyre: If a tyre loses pressure quickly, don’t drive! Pull over safely and call for roadside assistance or a tow truck.
Bonus Tips
- Check your tyre pressure regularly, not just when the warning light comes on.
- Rotate your tires every 5,000 miles to ensure even wear and tear.
- Invest in a quality tyre pressure gauge for accurate readings.
