Reset Ford Fiesta Tyre Pressure Light

Tyre pressure monitoring systems (TPMS) are a safety feature that warns the driver that one or more tyres has deflated to 25% or more of the set pressure. The tyre pressure light in the Ford Fiesta may need to be reset due to the monitoring system being triggered, yet the light is remaining on after remedial action.

To reset the tyre pressure warning light, follow these instructions:

1. Using the instrument panel in the middle, press the menu button.
2. Press the down arrow and scroll down to Vehicle settings and press OK.
3. Scroll down to Tyre monitoring and press OK.
4. Now press and hold the OK button.
5. Wait for a few seconds until you see the message ‘Tyre pressure reset‘.

That’s it, the Ford Fiesta tyre pressure light should now go out. If it remains on or comes back on again, you’ll need to check for other faults.

Ford Fiesta Tyre Pressure Warning Light Faults

Description	Action
Under-inflated Tyres	Ensure that all tyres are at the correct pressure. You can find the correct pressures on the tyre pressure label located on the inside door B-pillar. After inflating the tyres to the correct pressure, you will need to carry out the tyre pressure monitoring system reset procedure.
Spare Tyre is in Use	Using your spare tyre will trigger the Ford Fiesta tyre pressure monitoring system (TPMS). Repair your usual road wheel and tyre to restore normal operation. Light may be solid or flash.
Tyre Pressure Monitoring System Fault	If your tyres are set to the correct pressure, you have reset the TPMS and your spare tyre is not in use, there is a malfunction with the TPMS. Light will flash for approximately 1 minute with ignition ON and then remain stable.

Tyre Pressures

You should perform a system reset of the TPMS each time you adjust tyre pressures. Tyre pressures should be checked every two weeks, particularity when it is cold. Tyre pressures are lower when cold, often triggering the tyre pressure monitoring system. Driving with under-inflated tyre pressures can:

• Reduce vehicle stability
• Reduce braking ability
• Increase fuel consumtion
• Increase tyre wear

Changing Tyres

You must carry out the tyre pressure monitoring system reset each time you have a tyre changed on your vehicle.

Changing Wheels

If you intend on changing your wheels, the tyre pressure monitoring system will need to re-learn pressure sensors to avoid continually triggering a fault.

1. Make sure all tyres are inflated to the correct pressure.

1. Park up and allow your vehicle to rest for at least 20 minutes.

1. Carry out the tyre pressure monitoring system reset procedure.
2. The tyre pressure minitoring system will now re-learn the new pressure sensors for your Ford Fiesta the next time you drive for around 15 minutes and above a speed of 25 mph.

Tyre Pressure Montoring System Malfunction

If all tyres are running the correct pressures, you have reset the TPMS and the spare tyre is not in use, it’s likely that you have a malfunction with one or more of your sensor located in the tyres. These monitoring systems are sealed units meaning that sensors or batteries cannot be replaced independently and the whole unit should be replaced.
