Our goal is to ensure your Ford Explorer remains a reliable partner for your daily commutes, family road trips, and weekend off-road adventures. Let’s get started by preparing your vehicle and understanding the logic behind the reset process.
Why Your 2017 Ford Explorer Tire Pressure Light Stays On
Before you jump into the reset procedure, it is essential to understand why the light triggered in the first place. The TPMS in your Explorer is a direct system, meaning there is a physical sensor inside each wheel measuring actual air pressure. If the light is on, it usually means the pressure in one or more tires has dropped 25% below the recommended PSI (pounds per square inch).
Temperature swings are the most common culprit for a “false” alarm. When the air gets cold, it becomes denser, leading to a natural drop in pressure that might trigger the sensor. Conversely, if the light flashes for 60 to 90 seconds before staying solid, you likely have a system malfunction rather than just low air. This often points to a dead sensor battery or a communication error with the vehicle’s computer.
Another common scenario occurs after a tire rotation. The computer still thinks the “front left” sensor is in the front left position, even if it is now on the rear right. This is why a 2017 ford explorer tire pressure sensor reset is required; it teaches the car the new physical location of each specific sensor ID.
Step-by-Step 2017 ford explorer tire pressure sensor reset Procedures
There are two primary ways to put your Explorer into “Train Mode.” The first is a manual sequence involving the ignition and brake pedal, and the second involves the hazard light button. Both methods aim to get the vehicle to chirp its horn, signaling it is ready to learn.
The Ignition and Brake Pedal Method
- Ensure all tires are inflated to the pressure listed on the driver’s side door jamb sticker.
- Start with the ignition in the OFF position.
- Press and release the brake pedal once.
- Turn the ignition from OFF to RUN (the position just before starting the engine) three times, ending in the RUN position.
- Press and release the brake pedal again.
- Turn the ignition to the OFF position.
- Turn the ignition from OFF to RUN three more times, ending in the RUN position.
If done correctly, the horn will sound once, and the message center will display “Train Left Front Tire.” This confirms you have successfully initiated the 2017 ford explorer tire pressure sensor reset sequence. You now have about two minutes to trigger the first sensor before the system times out.
The Hazard Light Method
If the pedal dance feels too complicated, some 2017 models respond to the hazard light shortcut. With the ignition OFF, turn the key to the ON/RUN position without starting the engine. Quickly press the hazard light button six times within five seconds. If the vehicle enters training mode, the horn will honk, and you can begin the relearn process at the front left wheel.
How to Trigger the Sensors During Relearn
Once the vehicle is in training mode, you must “wake up” each sensor so it sends its unique ID to the car’s receiver. You must follow a specific order: Front Left, Front Right, Rear Right, and Rear Left. Never skip this order, or the dashboard will display the wrong tire location during a future pressure loss.
Using a TPMS Activation Tool
The most reliable way to trigger a sensor is with a dedicated TPMS tool. These are inexpensive handheld devices that send a radio frequency (RF) signal to the sensor. Hold the tool against the tire sidewall, right next to the valve stem, and press the button. The vehicle will honk to confirm it has “seen” the sensor. Move to the next tire in the sequence until all four are recognized.
The “Letting Air Out” Method
If you do not have a tool, you can trigger the sensors by rapidly changing the air pressure. Once the car is in training mode, go to the front left tire and let air out of the valve stem for about 10 to 15 seconds. Wait for the horn to honk. This method is slower and requires you to have an air compressor handy to refill the tires afterward, but it works in a pinch for DIYers.
Essential Tools for a Successful Reset
While you can technically perform a 2017 ford explorer tire pressure sensor reset without specialized gear, having the right tools makes the job faster and more accurate. As an enthusiast, I always recommend keeping a small kit in your garage for these routine tasks.
- Digital Tire Pressure Gauge: Accuracy is key; analog gauges can be off by 2-3 PSI, which is enough to keep the light on.
- TPMS Activation Tool: Look for a tool compatible with Ford’s 315MHz or 433MHz frequencies.
- Portable Air Compressor: Vital if you use the “air down” method to trigger your sensors.
- Valve Core Tool: Useful if you need to replace a leaking valve core before resetting the system.
Using a high-quality gauge ensures that you are starting from a known baseline. If your tires are unevenly inflated, the system may struggle to calibrate correctly. Always check the pressure when the tires are “cold,” meaning the car hasn’t been driven for at least three hours.
Common Challenges and Troubleshooting Tips
Sometimes, despite following the steps perfectly, the 2017 ford explorer tire pressure sensor reset fails. Do not get frustrated; there are several logical reasons why the system might be stubborn. One of the most common issues is signal interference from other electronics. Ensure you aren’t parked near a large microwave tower or using a cheap USB charger in the 12V outlet, as these can block the sensor’s RF signal.
Another factor is the age of the sensors. The lithium batteries inside TPMS sensors typically last 5 to 10 years. Since your Explorer is a 2017 model, you are entering the window where these batteries may begin to fail. If one sensor refuses to “train” while the others work fine, the battery is likely dead, and the entire sensor unit must be replaced.
Lastly, check for aftermarket equipment. If you have recently installed LED headlights or a new dashcam, the electrical noise might be interfering with the TPMS receiver located in the Smart Junction Box. Try unplugging aftermarket accessories before attempting the reset again.
Off-Roading and TPMS Considerations
For the off-road enthusiasts in the EngineNeeds community, the TPMS presents a unique challenge. When you “air down” your tires to 15 or 20 PSI for better traction on sand or rocky trails, the TPMS light will inevitably scream at you. This is normal and expected behavior for the system.
While you are on the trail, you can usually ignore the light, but you must be diligent about re-inflating before hitting the pavement. Driving on under-inflated tires at highway speeds causes excessive heat buildup, which can lead to a catastrophic tire blowout. Once you have aired back up to factory specs, you might need to perform a 2017 ford explorer tire pressure sensor reset if the light doesn’t clear itself after a few miles of driving.
If you frequently travel off-road, consider an OBDII programmer. Some advanced tools allow you to temporarily lower the “low pressure” threshold in the vehicle’s computer, preventing the light from coming on during your adventures. However, always remember to set it back to factory levels for street use.
When to Consult a Professional Mechanic
While DIY is the heart of EngineNeeds, there are times when a professional touch is necessary. If you have successfully entered training mode but the vehicle refuses to acknowledge a specific wheel even with a tool, the sensor might be physically damaged. This often happens during tire mounting if the technician isn’t careful with the tire iron.
If you see a “TPMS Fault” message that persists after multiple reset attempts, there could be an issue with the Body Control Module (BCM) or the antenna that receives the sensor signals. A licensed technician can use a high-end diagnostic scanner to “ping” the sensors and see exactly what the computer is seeing. If you find yourself in this position, it is safer to have a pro diagnose the electronics than to start guessing and replacing expensive parts.
Safety First: The Importance of Correct PSI
The TPMS isn’t just a convenience feature; it is a critical safety component. Under-inflated tires increase your braking distance and negatively impact your vehicle’s handling, especially in emergency maneuvers. Furthermore, running the wrong pressure leads to uneven tread wear, forcing you to buy new tires much sooner than necessary.
By mastering the 2017 ford explorer tire pressure sensor reset, you are taking an active role in your vehicle’s safety and longevity. It allows you to verify that the system is functioning as intended, giving you peace of mind whether you are dropping the kids off at school or exploring a remote forest road.
Always double-check your work. After performing a reset, drive the vehicle for 10-15 minutes at speeds above 20 mph. This allows the system to finalize the data and ensures the light stays off. If the light returns, re-check your pressures with a manual gauge to rule out a slow leak from a nail or a faulty valve stem.
Frequently Asked Questions About 2017 ford explorer tire pressure sensor reset
Can I reset the TPMS light without a tool?
Yes, you can use the “Ignition and Brake Pedal” method to enter training mode and then let air out of each tire to trigger the sensors. However, you will need a way to pump the tires back up afterward. This manual method is a great workaround if you don’t want to buy extra equipment.
Why does my TPMS light flash and then stay solid?
A flashing light for the first 60-90 seconds usually indicates a system fault rather than low pressure. This is often caused by a dead sensor battery, a broken sensor, or interference with the radio signal. A solid light from the start typically means one or more tires are simply low on air.
Do I need to reset the TPMS after every tire rotation?
Yes, it is highly recommended. While the sensors will still monitor pressure, the vehicle’s computer will have the wrong locations for the tires. If your rear right tire goes flat, the dashboard might tell you it is the front left, which can be confusing and potentially dangerous in a roadside emergency.
Will disconnecting the battery reset the tire pressure light?
No, disconnecting the battery will not permanently clear a TPMS light on a 2017 Ford Explorer. The system stores the fault codes in non-volatile memory. The only way to clear the light is to fix the underlying pressure issue or replace the faulty sensor and perform the proper relearn procedure.
What is the correct tire pressure for a 2017 Ford Explorer?
For most 2017 Ford Explorers, the recommended pressure is 35 PSI. However, you should always check the white and yellow sticker located on the driver’s side B-pillar (the door frame). This sticker provides the most accurate information for your specific trim level and tire size.
