2017 Ford Explorer Tire Pressure Sensor Replacement
Replacing a faulty tire pressure sensor on your 2017 Ford Explorer is a manageable DIY task that eliminates annoying dashboard warnings and ensures your tires remain at optimal inflation. This guide covers the entire process, from breaking the tire bead to performing the final computer relearn procedure.
Few things are more frustrating than seeing that glowing yellow horseshoe light on your dashboard every time you start your SUV. If you have checked your air levels and the light persists, you are likely dealing with a dead battery or a failed internal component in the wheel. Performing a 2017 ford explorer tire pressure sensor replacement is the most effective way to restore your peace of mind and vehicle safety.
You do not need to be a master technician to handle this job, but you do need the right sequence of steps. Whether you are prepping for a long highway road trip or getting ready for some light off-roading, having an active Tire Pressure Monitoring System (TPMS) is vital. In this guide, we will walk through the tools, the physical labor, and the digital handshake required to get your Ford back in top shape.
Safety is our primary concern here at EngineNeeds, so we will highlight the critical points where caution is mandatory. By following these professional steps, you can save a significant amount of money compared to dealership rates. Let’s dive into the specifics of getting your Explorer’s sensors back online.
Why You Need a 2017 ford explorer tire pressure sensor replacement
The TPMS in your Ford Explorer is a direct system, meaning there is a physical sensor mounted inside each wheel. These sensors use small lithium batteries that typically last between five and ten years. Since your vehicle is a 2017 model, many of these original batteries are now reaching the end of their functional life.
When a sensor fails, it stops transmitting data to the vehicle’s Body Control Module (BCM). This results in a “Tire Pressure Sensor Fault” message or a flashing light that eventually turns solid. Ignoring this can lead to poor fuel economy, uneven tire wear, and even dangerous blowouts if a slow leak goes unnoticed.
If you are an off-road enthusiast who frequently “airs down” for traction, your sensors endure even more stress. Constant pressure fluctuations and trail vibrations can cause the valve stem or the sensor body to crack. A timely replacement ensures that when you air back up for the pavement, your SUV knows exactly where your pressures stand.
Essential Tools and Parts for the Job
Before you begin, you need to gather specific tools to avoid getting stuck halfway through the process. You will need a high-quality floor jack and a set of sturdy jack stands to support the vehicle safely. Never work on a vehicle supported only by a jack.
For the tire work itself, a valve core tool is necessary to deflate the tire quickly. You will also need a bead breaker; while professional shops use a machine, DIYers can often use a heavy-duty C-clamp or even a second vehicle and a piece of wood to carefully break the tire’s seal. A torque wrench is also vital for tightening the lug nuts and the sensor nut to factory specifications.
Regarding parts, the 2017 Explorer typically uses a 315MHz sensor. Always verify your specific trim and build date, as some late-year models or specific exports might vary. Finally, you will need a TPMS relearn tool (often called a “clicker”) to sync the new sensor to the Ford’s computer system.
Recommended Parts List:
- New 315MHz TPMS Sensor (Motorcraft or high-quality aftermarket).
- Replacement valve stem (if not included with the sensor).
- Tire mounting lubricant or soapy water.
- New valve core and cap.
How to Perform a 2017 ford explorer tire pressure sensor replacement
The first step is to identify which sensor has failed. Most modern scanners can tell you which wheel is “dark.” Once identified, loosen the lug nuts while the tire is still on the ground, then jack up the vehicle and secure it on jack stands.
Remove the wheel and lay it flat on the ground. Use your valve core tool to remove the core and completely deflate the tire. You must break the “bead” (the seal between the tire and the rim) only on the side where the sensor is located. Use your bead breaker or C-clamp to push the tire rubber down about 4-6 inches away from the valve stem to avoid crushing the old sensor.
Once the bead is pushed down, you will see the sensor attached to the valve stem inside the rim. Use a small socket or wrench to unscrew the nut holding the stem in place. Carefully pull the old sensor out through the gap between the tire and the rim. This is a great time to clean the mounting hole to ensure a leak-free seal for the new unit.
Insert the new sensor, ensuring the rubber grommet is seated correctly against the rim. Tighten the mounting nut—usually to about 35-45 inch-pounds. Do not over-tighten, as you can crack the new sensor body. Once secure, re-inflate the tire until the bead “pops” back into place, then set it to the recommended PSI found on your driver-side door jamb.
The Relearn Procedure: Syncing with the BCM
Physical installation is only half the battle. Your Ford Explorer needs to “meet” the new sensor. Without this digital handshake, the light will stay on. There are two ways to do this: the manual “brake pedal dance” or using a dedicated TPMS trigger tool.
To enter relearn mode manually, turn the ignition to the “OFF” position, then press and release the brake pedal. Turn the ignition from “OFF” to “RUN” (not start) three times, ending in “RUN.” Press and release the brake pedal again, then turn the ignition “OFF.” Finally, turn it to “RUN” three more times. If done correctly, the horn will honk, and the dash will display “Train Left Front Tire.”
Now, take your TPMS relearn tool to the front left tire and hold it against the sidewall near the valve stem. Press the button on the tool. The horn will honk once to confirm it has recognized the sensor. Repeat this for the front right, rear right, and finally the rear left. Once the final tire is recognized, the dash will show “Training Complete.”
Pro Tip for Off-Roaders:
If you frequently change wheel sets for trail use, consider buying a dedicated TPMS programming tool. This allows you to “clone” the IDs of your street sensors onto your off-road set. This prevents the need to perform a 2017 ford explorer tire pressure sensor replacement or relearn every time you swap tires for the weekend.
Common Mistakes to Avoid
One of the most frequent errors is damaging the new sensor during tire mounting. If you are taking the wheel to a shop to have the tire mounted, tell the technician explicitly that there is a new TPMS sensor installed. They must position the tire machine’s “duckhead” correctly to avoid snapping the plastic sensor body.
Another pitfall is using the wrong frequency sensor. As mentioned, most 2017 Explorers use 315MHz, but some heavy-duty or specialized versions might differ. Always check your VIN or the part number on the old sensor before ordering a replacement. Using a 433MHz sensor on a 315MHz system will result in a sensor that physically fits but never communicates.
Finally, never reuse an old rubber grommet or valve nut. These components are designed to crush slightly to create a seal. Reusing old hardware is a recipe for a slow air leak that will have you pulling the tire off all over again. Most new sensors come with a fresh service kit—use it!
Maintenance and Long-Term Care
To keep your sensors healthy, always use plastic valve caps. Metal caps can undergo galvanic corrosion with the aluminum valve stem, essentially welding themselves in place. If you have to use pliers to remove a cap, you risk snapping the stem and needing another 2017 ford explorer tire pressure sensor replacement.
Check your tire pressures manually at least once a month. While the TPMS is a fantastic safety net, it is not a substitute for a high-quality pressure gauge. Cold weather can cause pressures to drop, often triggering a “false” light. Knowing your baseline pressure helps you distinguish between a weather-related drop and a genuine sensor failure.
If you live in the “Salt Belt” where roads are salted in winter, wash your wheels regularly. Salt and road brine can eat away at the aluminum threads of the valve stem. A little bit of preventative cleaning goes a long way in extending the life of your expensive electronic components.
Frequently Asked Questions About 2017 ford explorer tire pressure sensor replacement
Can I replace just the battery in the sensor?
No, the batteries in these sensors are encased in a potting epoxy to protect them from moisture and vibration. Attempting to dig the battery out usually destroys the circuitry. It is much more reliable and cost-effective to replace the entire unit.
Will the TPMS light reset itself after I put air in the tires?
Usually, yes. If the sensor is healthy and the pressure is corrected, driving the vehicle above 20 mph for about 10 minutes should allow the light to turn off. If it stays on or flashes, you likely need a 2017 ford explorer tire pressure sensor replacement.
Can I drive with a faulty TPMS sensor?
You can physically drive the vehicle, but it is not recommended. You lose the early warning system for leaks and blowouts. Additionally, in some regions, a glowing TPMS light will result in an automatic safety inspection failure.
Do I need to replace all four sensors at once?
While not strictly necessary, it is often a good idea. Since all four sensors were installed at the factory at the same time, their batteries are likely to fail within months of each other. Replacing them as a set saves you from multiple trips to the shop or multiple weekend DIY sessions.
Final Thoughts on Your DIY Project
Taking ownership of your vehicle’s maintenance is a rewarding experience. Successfully completing a 2017 ford explorer tire pressure sensor replacement not only saves you money but also deepens your understanding of how your SUV operates. It ensures that your Ford remains a reliable partner for daily commutes and weekend adventures alike.
Remember to always prioritize safety by using proper lifting equipment and following torque specifications. If you feel uncomfortable breaking the tire bead yourself, you can always bring the wheel and your new sensor to a local tire shop; they will often install it for a small labor fee. Either way, getting that light off your dash is a win for your vehicle’s longevity.
Stay safe on the road, keep those pressures checked, and enjoy the smooth ride of your Ford Explorer! For more DIY guides and off-road setup tips, keep exploring EngineNeeds.
