2017 Ford Explorer Tire Pressure Sensor Fault – Diagnosis And DIY

ByRobert Lozano

Experiencing a “2017 Ford Explorer tire pressure sensor fault” can be a puzzling and sometimes concerning issue. This warning light indicates a problem with your vehicle’s Tire Pressure Monitoring System (TPMS), which could be a simple sensor issue, a low tire, or something more complex. This guide will help you understand the common causes and walk you through troubleshooting steps.

Your 2017 Ford Explorer uses a sophisticated Tire Pressure Monitoring System (TPMS) to alert you to underinflated tires, a crucial safety feature. When the TPMS warning light illuminates, often displaying a “tire pressure sensor fault” message, it means the system has detected an issue. This could range from a simple fix like a dead sensor battery to a more involved problem requiring professional attention.

Decoding the TPMS Warning Light on Your 2017 Ford Explorer

The first step in addressing a “2017 ford explorer tire pressure sensor fault” is understanding what the light signifies. This system is designed to enhance safety by preventing driving on underinflated tires, which can affect handling, fuel economy, and increase the risk of a blowout. When the light illuminates, it’s not just an annoyance; it’s a signal that something needs your attention.

The TPMS on your Explorer consists of sensors within each wheel that monitor air pressure and transmit this data wirelessly to the vehicle’s computer. If one of these sensors malfunctions, its battery dies, or it loses its connection, the system will report a fault. It’s important to distinguish between a low tire pressure warning and a sensor fault warning, though they can sometimes appear similar.

Common Causes for a 2017 Ford Explorer Tire Pressure Sensor Fault

When that persistent TPMS light appears, it’s usually due to one of a few common culprits. Pinpointing the exact cause can save you time and money in repairs. Don’t immediately assume the worst; often, the fix is straightforward.

Dead Sensor Batteries

The TPMS sensors inside your tires are battery-powered. These batteries are designed to last for several years, typically between 5 to 10 years, depending on usage and environmental factors. When a battery dies, the sensor can no longer transmit its pressure readings, triggering a “tire pressure sensor fault” on your dashboard. This is one of the most frequent reasons for the warning light.

Damaged or Faulty TPMS Sensors

Beyond just dead batteries, the sensors themselves can fail. They are exposed to the elements, road debris, and impacts. A hard pothole hit or even the process of tire changes can sometimes damage a sensor. If a sensor is physically damaged or has an internal electronic failure, it will report an error.

Improper Tire Inflation or Reset Procedures

Sometimes, the issue isn’t a faulty sensor but rather how the system is being interpreted. After inflating your tires to the correct pressure (check the sticker on your driver’s side doorjamb), the TPMS system usually needs to be reset. If this reset procedure isn’t performed correctly, or if the tires are significantly underinflated, the system might report a fault even if the sensors are working.

Issues with the TPMS Receiver or Control Module

While less common, the problem might lie with the TPMS receiver or the vehicle’s central control module that processes the sensor data. Interference from other electronic devices, water damage, or internal module failure can disrupt the communication between the sensors and the vehicle.

Troubleshooting Steps for a 2017 Ford Explorer Tire Pressure Sensor Fault

Before heading to a mechanic, there are several troubleshooting steps you can take yourself to diagnose the “2017 ford explorer tire pressure sensor fault.” These steps are designed to be safe and accessible for the average car owner.

Step 1: Check Tire Pressures Manually

The most crucial first step is to check the air pressure in all four tires, plus the spare if applicable. Use a reliable tire pressure gauge. Ensure the tires are cold (driven less than a mile) for the most accurate reading. Inflate or deflate them to the manufacturer’s recommended PSI, which is usually found on a sticker inside the driver’s side doorjamb.

Step 2: Perform the TPMS Reset Procedure

After adjusting tire pressures, you’ll likely need to reset the TPMS. The exact procedure can vary slightly, but for many Ford vehicles, it involves a sequence of turning the ignition on and off, and sometimes pressing and holding a button. Consult your owner’s manual for the specific steps for your 2017 Explorer.

Step 3: Inspect TPMS Sensors (Visual Check)

While you can’t easily access the internal sensors without removing the tires, you can visually inspect the valve stems where the sensors are located. Look for any obvious signs of damage, corrosion, or if a valve stem appears loose.

Step 4: Drive the Vehicle to Allow Relearning

After resetting and ensuring correct tire pressures, drive your Explorer at speeds above 20 mph for at least 10-15 minutes. This allows the TPMS sensors to transmit their readings and the system to relearn them. The warning light should turn off if the issue was simply a pressure fluctuation or a need for a reset.

When to Seek Professional Help for Your TPMS Fault

If you’ve gone through the basic troubleshooting steps and the “2017 ford explorer tire pressure sensor fault” persists, it’s time to involve a professional. There are specific tools and knowledge required to diagnose and repair more complex TPMS issues.

Diagnosing with a TPMS Scan Tool

Automotive repair shops and tire shops are equipped with specialized TPMS scan tools. These tools can communicate directly with the TPMS control module and each sensor. They can read sensor IDs, battery life, pressure readings, and identify specific sensor failures or communication errors.

Replacing a Faulty TPMS Sensor

If a scan tool identifies a specific sensor as faulty or having a dead battery, it will need to be replaced. This typically involves dismounting the tire from the wheel to access the sensor. Many modern sensors are integrated units, meaning the entire sensor assembly is replaced.

Programming New Sensors

After installing a new TPMS sensor, it often needs to be programmed to your vehicle’s TPMS module. This involves registering the new sensor’s unique ID so the car’s computer recognizes it. This process requires specialized programming equipment and is best done by a qualified technician.

Understanding TPMS Sensor Lifespan and Maintenance

The TPMS is a crucial safety system, and understanding its components can help you maintain it effectively. Proactive awareness can prevent unexpected “2017 ford explorer tire pressure sensor fault” messages.

Battery Life and Replacement Considerations

As mentioned, TPMS sensor batteries are not user-replaceable. When a battery dies, the entire sensor unit must be replaced. This is why the age of your sensors is a factor. If your Explorer is approaching or has passed the typical 7-10 year lifespan for sensors, be prepared for potential replacements.
