Why is my Ford tire pressure light still on after filling the tires?

Either one tire is still below the placard pressure (check the spare too on cars that monitor it), the system needs to relearn, or a sensor battery has died. Sensors last about 7 to 10 years.

What pressure should the tires be?

Use the label on the driver's door jamb, not the number on the tire sidewall. The sidewall figure is the tire's maximum, not the car's setting.

Ford tire pressure light reset

To reset the tire pressure light on a Ford (Models with a tire-monitor screen in the instrument cluster): Switch the ignition on. Navigate to the tire monitor menu in the information display. Press and hold the OK button until a confirmation message appears (or press and hold the physical TPMS reset button if the vehicle has one instead).

Key takeaways

Inflate every tire to the door-jamb pressure first - the light is telling you something.

Some years need an OBD-II or TPMS tool - no button sequence exists.
If it does not work, confirm your exact year in the owner's manual.

Needs an OBD-II or TPMS tool

Turn the ignition off, then press and release the brake pedal.
Cycle the ignition from OFF to RUN three times, ending in RUN, without waiting more than two minutes between cycles.
Press and release the brake pedal again, then repeat the three-cycle ignition sequence once more.
When the message center (if equipped) shows 'TRAIN LF TIRE', hold a TPMS activation tool at the valve stem of each tire in turn, waiting for the horn chirp before moving to the next.

This full sensor-training procedure needs a TPMS activation tool; it's the standard trade-shop method for anything beyond a simple pressure reset.

Tools that help

These fit any car. A gauge that reads to 0.5 psi takes the guesswork out of the relearn.
