How to Turn the Annoying Ford F-150 Tire Pressure Light Off

Do you feel that cool breeze? Fall is blowing some cooler temperatures in, and the tires on your Ford F-150 may have noticed. This may have caused the tire pressure warning light to turn on, but unfortunately, in the Ford F-150, it can be frustrating to get it to turn off.

Ford isn’t alone with its annoying tire pressure light. Tire pressure monitoring systems are government-mandated in America, so all vehicles have them. Only the particular system in the Ford F-150 can be annoying, despite it being helpful to know if one of your tires is deflated.

If your Ford F-150 has a tire pressure monitoring system (TPMS) alert, then a TPMS warning light will be illuminated. Once you see it, be sure to check your tire pressure. Some vehicles can display the tire-pressure information, but if your F-150 doesn’t, check each tire manually with a tire pressure gauge. 

You’ll find what pressure the tires should have on the driver’s door. Do not drive your truck until the tires have the proper air pressure. Driving with under-inflated tires could cause premature wear, tread separation, and blowouts.

You may notice that your TPMS light is on after a sudden cold front comes in. This could be due to having your tire pressure set during different temperatures as the pressure inside the tires drops as it gets colder. 

According to TorqueNews, the Ford manual states that if a vehicle is left overnight with temperatures significantly lower at night during the day, the tire pressure may drop by 3 psi. So, if you find your tires to be lower than the setpoint, add air to get them to the correct pressure. Then the TPMS light should turn off. 

Your Ford F-150 has a flat 

If only one tire is under-inflated, have it checked out by a technician. The Ford F-150 TPMS will detect a flat tire and provide a warning light for it. The light may come on before you leave or while you’re driving. Be sure to pull over and investigate as soon as you see the warning indicator.

Check the pressure of each tire, and if you have a flat refer to your Ford F-150 owner’s manual for instructions on what to do next. You may need to switch to your spare tire and can call roadside assistance for help. 

What if your Ford F-150 TPMS fails? 

Sometimes the TPMS in your Ford F-150 can fail. Things like loose electrical connections and wear and tear with age can happen. But your TPMS will alert you once it fails. The light will flash for one minute, then remain illuminated.

If you check each tire’s pressure with a gauge and the tires are at their recommended pressure, go to a mechanic for help. You don’t have to go to a Ford dealership for service. However, this issue could be covered by your warranty, depending on how new your F-150 is. You can also use your manual to reset your TPMS light.
