This is a complete guide to diagnosing a TPMS (Tyre Pressure Monitoring System) issue on a Ford Fiesta MK 7.5. If the warning light is on but the tyre pressures are correct, the issue is likely a faulty TPMS sensor or a dead battery. Prepare the vehicle for 'sensor programming' mode.

With the engine off, press and release the brake pedal; turn the ignition on and then off. Repeat this sequence two more times, and finally leave the ignition on: press and release the brake pedal again. Turn the ignition off and on one last time; the vehicle will emit a beep and the TPMS light on the dashboard will flash for a few seconds.

The vehicle is now in relearn mode and awaits signals from each sensor, starting with the front left tyre. Now you need a programming tool, bring it close to the tyre valve (where the sensor is located) and if it is functioning, the vehicle will beep.

Repeat this for the front right, rear right, and rear left. If any sensor does not respond, that sensor is faulty or dead.

Replacement can only be done by a tyre specialist as it requires special equipment.
