Ford F150 Tire Pressure Sensor Fault

By Nick Marchenko, PhD

Tire pressure monitoring systems (TPMS) have been made compulsory in all American vehicles as a government-mandated measure aimed at bolstering road safety.

The primary purpose of TPMS is to monitor and display the air pressure within each tire continuously. This ensures that drivers are promptly alerted to any significant deviations from the recommended pressure levels, contributing significantly to overall safety on the roads.

While TPMS is a valuable safety feature, occasional malfunctions can occur, leading to unexpected frustration for vehicle owners. If you happen to own a Ford F150 and find yourself confronted with TPMS fault alerts on your dashboard, it is essential to address the issue promptly. Ignoring or neglecting TPMS faults can compromise the accuracy of tire pressure readings, potentially impacting safety.

To assist Ford F150 owners in effectively managing and resolving TPMS fault alerts, we have undertaken comprehensive research to provide valuable insights and practical tips.

By following the recommended steps, you can successfully address and turn off the bothersome TPMS fault alert, ensuring the continued reliability and accuracy of your tire pressure monitoring system.

What is a Tire Pressure Sensor?

Your car has a tire pressure sensor, which is an electrical device. These sensors monitor the air pressure in your tires and provide alarms when there is a problem with the tire pressure.

The prevalence of tire pressure sensors is growing in new vehicles, offering drivers the advantage of detecting problems at an early stage.

This proactive monitoring helps in preventing accidents and prolonging the lifespan of your tires. Tire pressure sensors are commonly referred to as TPMS, which stands for Tire Pressure Monitoring Systems.

What Does it Mean if a Ford F150 Displays a Tire Sensor Fault?

The tire sensor fault message is a common alert that may appear on your F150 cluster, signaling a potential issue with your tires. Tire pressure sensors are installed in each tire and are responsible for measuring air pressure and communicating this information to your vehicle's computer.

If one or more of these sensors fails, a tire pressure indication light will illuminate on your dashboard. When you receive this notification, perform the following actions:

1. Inspect all four tires for damage. If any tire displays a bulge or puncture, promptly seek the expertise of an experienced technician for immediate repair.
2. Examine all four tires for irregular wear patterns or cracks around the tread edges, commonly referred to as cupping. Such damage may indicate over-inflation or under-inflation, potentially leading to compromised handling and reduced fuel efficiency.
3. If indications of under-inflation or cupping are observed on one rear tire, extend the inspection to all four tires for similar issues before resuming operation of your pickup. This proactive approach ensures a comprehensive assessment and addresses potential problems before they escalate.

What are the Main Causes of Tire Sensor Fault on a Ford F150?

There are various reasons why your Ford F150 might display a tire pressure sensor fault on the dashboard. Here are some potential causes:

Faulty tire pressure sensor

The tire pressure sensor is an electronic device responsible for monitoring tire air pressure. It transmits signals to the onboard computer, which then displays tire pressure on the dashboard. If one of these sensors malfunctions or fails, it can trigger a low tire pressure warning light on the dash.

Tire pressure sensor memory loss

When your vehicle has been stationary for an extended period, certain systems, including the TPMS system, may lose power. Upon restarting your car, these systems should automatically reset and recalibrate. If this does not occur, it may indicate a faulty TPMS system that requires replacement.

Wheel change

Swapping out stock rims for aftermarket ones can pose challenges to the TPMS system. Aftermarket rims may not have the same mounting pattern as stock ones, even if they appear similar. This lack of compatibility with the car's built-in sensors can lead to TPMS issues.

Resetting Your Tire Pressure Light

If the TPMS light illuminates on your dashboard, begin by checking the tire pressure in each tire and inflating them to the recommended psi.

This information is typically found inside the driver's side door or in your owner's manual. If reinflating does not resolve the issue, consider the following steps:

Reset the TPMS sensor

Drive at least 50 MPH for 10 minutes to reset the TPMS sensor. Upon restarting the car, the light should no longer be illuminated.

Use the TPMS reset button

With the car battery on, but not the ignition, find the TPMS reset button, usually located beneath or near the steering wheel. Hold the button until the dashboard light blinks three times, release the button, start the ignition, and the TPMS light should be extinguished.

Overinflate and deflate tires

Inflate all tires, including the spare, to 3 PSI over the recommended level. Next, completely deflate them. Once deflated, reinflate each tire to the recommended pressure to reset the TPMS sensors.

Disconnect the positive battery cable

Turn off the engine, open the hood, and remove the positive battery cable using a wrench. Turn on the vehicle, honk the horn for three seconds, and then reconnect the battery.

This process is designed to discharge any stored power in the vehicle, leading to the disappearance of the TPMS light.

Can You Drive with a Tire Pressure Sensor Fault?

Driving with a Tire Pressure Monitoring System (TPMS) sensor fault can lead to serious safety problems. A TPMS warning light may illuminate on your dashboard, indicating that air pressure is low or that one or more of your tires has been damaged.

If you have a TPMS sensor fault and continue to drive, you risk severe tire damage or even blowouts that could cause an accident.

You should never drive with a TPMS sensor fault. If you observe a warning light lit on your dashboard and are unclear what it means, pull over as soon as it is safe to do so and tow your vehicle to a reputable expert as soon as possible for an assessment.

When working with a Ford F150, you may meet typical problems such as a faulty tire pressure sensor. As a responsible driver, having essential knowledge about tire pressure can alleviate recurring concerns and ensure a smoother experience with your vehicle.
