You may have experienced a tire pressure sensor fault in your Ford Edge at some point. This can be frustrating, as it can lead to inaccurate readings and even trigger the TPMS warning light on your dashboard. In this blog post, we’ll take a closer look at Ford Edge tire pressure sensor faults, what causes them, and how to fix them.

What is a Tire Pressure Sensor Fault?

First, let’s define what we mean by a tire pressure sensor fault. In modern vehicles, a tire pressure monitoring system (TPMS) is used to keep track of the air pressure in each tire. This system uses sensors mounted inside the tire valve stems to measure the pressure and send that information to the car’s computer.

A tire pressure sensor fault occurs when one or more of these sensors fails to transmit accurate data to the car’s computer. This can happen for a variety of reasons, including damage to the sensor, low battery life, or interference from other electronic signals.

Symptoms of a Tire Pressure Sensor Fault

The most obvious symptom of a tire pressure sensor fault is the TPMS warning light on your dashboard. This light will illuminate when the car’s computer detects that the pressure in one or more tires is too low, or if it is unable to receive data from one of the sensors.

In some cases, you may also notice that the readings on your tire pressure gauge or the car’s information display are incorrect. This can lead to overinflated or underinflated tires, which can cause problems with handling, fuel economy, and overall safety.

Causes of Ford Edge Tire Pressure Sensor Faults

There are several potential causes of tire pressure sensor faults in Ford Edge vehicles. Some of the most common include:

Battery Life

The sensors in your tires are powered by small batteries, which typically last around 5-7 years. When the battery dies, the sensor will no longer transmit data to the car’s computer.


The sensors in your tires are vulnerable to damage from road debris, potholes, and other hazards. If a sensor is physically damaged, it may not be able to transmit data accurately.

Electrical Interference

Your car’s electronic systems can generate electromagnetic interference that can disrupt the signals from the tire pressure sensors. This interference can be caused by a faulty alternator, radio, or other electronic components.

How to Fix a Ford Edge Tire Pressure Sensor Fault

If you’re experiencing a tire pressure sensor fault in your Ford Edge, there are several steps you can take to diagnose and fix the problem.

Check the Battery Life

If the sensors in your tires are more than 5 years old, it’s possible that the batteries have died. In this case, you’ll need to replace the sensors. You can purchase new sensors from a Ford dealership or online retailer.

Inspect for Damage

If you notice that one of your tires is consistently showing an incorrect pressure reading, it’s possible that the sensor has been damaged. You can inspect the sensor visually or use a multimeter to test its resistance. If the sensor is damaged, you’ll need to replace it.

Reset the TPMS System

In some cases, a tire pressure sensor fault can be caused by a temporary glitch in the TPMS system. To reset the system, you can follow these steps:

  • Make sure all tires are inflated to the correct pressure.
  • Turn the ignition to the “on” position.
  • Press and hold the TPMS reset button (located in the glove compartment) until the TPMS warning light blinks three times.
  • Release the button and wait for the light to stop blinking.

Address Electrical Interference

If you suspect that electrical interference is causing the tire pressure sensor fault, you’ll need to take your Ford Edge to a mechanic or dealership. They can perform diagnostic tests to identify the source of the interference and take steps to mitigate it. This may involve replacing faulty electronic components, adding shielding to wiring, or other measures.

Preventing Tire Pressure Sensor Faults

While some tire pressure sensor faults are unavoidable, there are steps you can take to reduce the likelihood of experiencing them:

Check Your Tire Pressure Regularly

By keeping your tires properly inflated, you can reduce the strain on the tire pressure sensors and extend their lifespan.

Be Careful on the Road

Avoid driving over potholes, speed bumps, and other hazards that could damage your tires or sensors.

Avoid Aftermarket Sensors

While it may be tempting to save money by purchasing aftermarket tire pressure sensors, these may not be as reliable as OEM parts. Stick with genuine Ford sensors to ensure the best performance and reliability.


A tire pressure sensor fault can be a frustrating issue for Ford Edge owners, but with the right knowledge and tools, it’s a problem that can be solved. Whether you need to replace a faulty sensor or address electrical interference, there are steps you can take to keep your TPMS system functioning properly. By taking care of your tires and sensors, you can enjoy a safer, more reliable driving experience in your Ford Edge.
