How to Reset the TPMS Light on a Ford
Fill every tire to the PSI on the driver's door-jamb sticker, then drive a few minutes. Still on? Run the relearn below.
Light flashes, then stays solid? → that's a sensor fault, not low air
First: Fix the Pressure
This clears most TPMS lights on its own.
- Find the right number. Open the driver's door and read the PSI on the door-jamb sticker. Don't use the number on the tire sidewall. That's the maximum, not the target.
- Fill all tires to spec while they're cold. Include the spare if your model monitors it. One low tire after a cold night is the usual trigger.
- Drive at least a few minutes above 20 mph. Most Fords turn the light off on their own once the sensors report correct pressure.
If the light flashes for about a minute at startup, then stays solid, the system has a fault: usually a dead sensor battery or a sensor that isn't communicating. Air won't fix it. Try the relearn below, then plan on a shop visit.
If It Stays On: The TPMS Relearn (Sensor Training)
Do this after a tire rotation, a sensor replacement, or when the pressure is right but the light won't quit. Most Fords use this ignition-cycle method and need a TPMS activation tool at each wheel.
- Inflate all tires to the door-jamb PSI.
- Ignition OFF. Press and release the brake pedal.
- Cycle the ignition from OFF to RUN three times, ending in RUN. Press and release the brake pedal.
- Turn the ignition OFF, then cycle OFF to RUN three more times, ending in RUN. The horn sounds once and the TPMS light flashes. You're in training mode.
- Within 2 minutes, hold the tool to the left-front sidewall at the valve stem until the horn chirps. Repeat at the right-front, right-rear, then left-rear tire, with no more than 2 minutes between tires.
- Turn the ignition OFF. If the message center shows training complete, or the horn stays silent, you're done. Two horn honks at shut-off mean a sensor didn't register. Start over.
Steps vary by model and year, and many newer Fords run the relearn from the message-center or SYNC menu instead. Your Owner's Manual (Wheels and Tires section) has the exact procedure for your vehicle.
Why the Light Comes On
| Cause | What fixes it |
|---|---|
| Low tire (often after a cold night) | Inflate to door-jamb spec, then drive to clear |
| Tires rotated | Run the TPMS relearn so wheel positions re-map |
| New tires or new sensors | Relearn with a tool, and confirm the sensors are the right type |
| Dead sensor battery | Replace the sensor (they last about 5 to 10 years) |
| Monitored spare is low | Inflate the spare too |
Newer Trucks Use Different Sensors
Some recent Fords, including the 2024 F-150, switched to a different TPMS sensor frequency. An older relearn tool or aftermarket sensor may not talk to them. If a relearn won't take on a newer Ford, that's often why, and the shop can confirm the right sensor and tool.
When It's a Shop Job
If the light won't clear after you've set the pressures and run the relearn, you likely have a failed sensor or a module that needs a scan. We have TPMS tools for every Ford. We find the bad sensor, replace it, and relearn the system, usually the same day. Diagnosis is backed by our 3-Hour Diagnosis Guarantee, with free pickup and delivery within 20 miles of Keyport.

Ford TPMS Light: FAQs
How do I reset the TPMS light on my Ford?
Set every tire to the PSI on the driver's door-jamb sticker and drive a few minutes above 20 mph. The light usually clears. If it doesn't, run the TPMS relearn for your model.
Why is my Ford tire pressure light still on after filling the tires?
It can take a few minutes of driving to clear, or the sensors may need a relearn after a rotation. If the pressure is correct and it still won't clear, a sensor may be failing.
What pressure should my tires be?
Use the PSI on the driver's door-jamb sticker, not the higher maximum printed on the tire sidewall.
Does the TPMS light reset itself?
Usually. Once the pressures are correct, a short drive lets most Fords clear it automatically.
Can I drive with the TPMS light on?
Only far enough to reach air or a shop. A lit light means a tire could be low, which affects handling, braking, and tire wear.
Why does my TPMS light come on in cold weather?
Air contracts as it cools, dropping about 1 PSI for every 10°F. A cold morning can push a tire below the warning threshold. Top it off and the light usually clears.
The light flashes, then stays on. What does that mean?
A light that flashes at startup and then turns solid points to a system fault, often a dead sensor, not low pressure. It usually needs a scan.
Do I need a tool to reset TPMS after rotating tires?
Usually yes. A TPMS activation tool wakes each sensor during the relearn so the system can re-map the wheel positions.
How long do TPMS sensors last?
About 5 to 10 years. The battery is sealed inside, so a dead battery means a new sensor.
Will new tires turn the light off?
Only if the sensors are working and have been relearned. New tires alone don't reset the system.
