2020 Ford Explorer TPMS Reset – The Definitive DIY Guide To Clearing
Resetting the Tire Pressure Monitoring System (TPMS) on your 2020 Ford Explorer is a vital maintenance task that ensures your vehicle’s safety sensors are calibrated correctly. This guide provides the exact sequences needed to clear dashboard warnings and relearn sensor positions after a tire rotation or replacement.
Do you find it frustrating when that yellow horseshoe light stays illuminated even after you have filled your tires? You are not alone, as many Ford owners struggle with the nuances of the 2020 ford explorer tpms reset procedure.
The good news is that you do not need to pay a dealership for a simple software reset. This article will provide you with the professional-grade steps to handle this task in your own garage using simple sequences or affordable tools.
By the end of this guide, you will understand the different reset methods, the tools required, and how to troubleshoot stubborn sensors that refuse to communicate with your vehicle’s computer.
Understanding the Importance of the 2020 ford explorer tpms reset
The TPMS in your Explorer is a safety-critical system designed to alert you when a tire’s internal pressure drops 25% below the recommended cold inflation pressure. For a modern SUV like the 2020 Explorer, maintaining correct pressure is essential for stability, braking distance, and fuel economy.
When you perform a 2020 ford explorer tpms reset, you are essentially telling the Body Control Module (BCM) to look for new data points from the sensors located inside the wheel assemblies. This is especially important after a tire rotation because the computer needs to know which sensor is now at the front-left versus the rear-right.
Failure to reset the system can lead to inaccurate dashboard displays. You might see a warning for the front-left tire when the actual problem is in the rear, leading to confusion and potential safety hazards during a roadside emergency.
Preparation: Setting the Correct PSI Before the Reset
Before you begin any reset procedure, you must ensure your tires are actually at the correct pressure. Attempting to reset the system with incorrectly inflated tires will only result in the light returning a few miles down the road.
Open the driver’s side door and look at the B-pillar for the Tire and Loading Information placard. This sticker lists the exact PSI (pounds per square inch) required for your specific trim level, whether you drive the XLT, Limited, or the high-performance ST model.
Use a high-quality digital pressure gauge to check the tires while they are “cold,” meaning the car has been parked for at least three hours. If you have been driving, the friction creates heat, which artificially raises the pressure reading inside the tire carcass.
- Check the spare tire if your Explorer is equipped with a full-size spare, as some systems monitor it too.
- Ensure your valve stem caps are clean and free of corrosion.
- Adjust all four main tires to the exact PSI listed on the door jamb.
The Step-by-Step 2020 ford explorer tpms reset Process
There are two primary ways to approach the 2020 ford explorer tpms reset. The first is a simple software “clear” through the dashboard menu, and the second is a “relearn” or “training” mode used when sensors have moved positions.
Method 1: The Dashboard Menu Reset
This method is best used after you have simply added air to a low tire. It tells the computer to re-evaluate the current pressures and confirm they are within the acceptable safety threshold.
- Sit in the driver’s seat and close all doors.
- Push the “Start” button without pressing the brake pedal to enter Accessory Mode.
- Use the steering wheel toggle buttons to navigate to the “Settings” menu on the digital cluster.
- Select “Information” and then scroll down to “Tire Pressure.”
- Press and hold the “OK” button until the system indicates the reset is complete.
Method 2: The Training Mode (Hazard Light Sequence)
If you have rotated your tires or installed new sensors, you need the “Training Mode.” This tells the vehicle’s radio frequency receiver exactly where each sensor is located on the chassis.
To enter this mode, turn the ignition to the OFF position, then press and release the brake pedal. Quickly cycle the ignition from OFF to RUN (don’t start the engine) three times, ending in the RUN position.
Press and release the brake pedal again, then turn the ignition to OFF. Finally, cycle the ignition from OFF to RUN three more times; the horn will honk once to signify that the 2020 ford explorer tpms reset training mode is active.
Using a TPMS Relearn Tool for Faster Results
While you can “train” the sensors by letting air out of the tires until the horn honks, using a dedicated TPMS activation tool is much more efficient. These tools send a specific 125kHz signal to “wake up” the sensor and force it to transmit its ID to the car.
For the 2020 Ford Explorer, you can use an inexpensive Ford-specific tool (often called a “clicker”). You simply point the tool at the sidewall of the tire near the valve stem and press the button while the car is in training mode.
Start with the driver’s side front tire. Once the horn honks, move clockwise to the passenger front, then passenger rear, and finally the driver’s side rear. This sequential mapping ensures the car’s computer knows exactly which corner of the vehicle corresponds to which sensor ID.
Investing $15 to $20 in one of these tools is a smart move for any DIY mechanic. It saves you from having to refill all four tires after performing a manual pressure-drop training sequence.
Troubleshooting Common TPMS Issues on the Explorer
Sometimes, despite your best efforts, the 2020 ford explorer tpms reset fails to stick. This is often due to hardware issues rather than a mistake in your reset procedure.
One common culprit is a dying sensor battery. Most TPMS sensors use small lithium-ion batteries that are designed to last 5 to 10 years; however, extreme cold or high mileage can shorten this lifespan significantly.
If one specific tire refuses to “train” during the sequence, that sensor is likely dead or damaged. You should also check for aftermarket electronic interference, such as cheap USB chargers or dashcams, which can sometimes block the RF signal from the sensors to the BCM.
Identifying Sensor Faults vs. Low Pressure
It is important to distinguish between a “Low Tire Pressure” warning and a “TPMS Fault” message. A low-pressure warning usually stays solid, while a system fault often flashes for 60 to 90 seconds when you start the car before staying solid.
A flashing light almost always indicates a communication error or a hardware failure. In these cases, a simple reset won’t work until the faulty sensor is replaced by a professional tire shop.
Off-Roading and TPMS: What You Need to Know
For the off-road enthusiasts using their 2020 Explorer for light trails or beach driving, TPMS presents a unique challenge. When you “air down” to 15 or 20 PSI to increase your contact patch on sand, your dashboard will light up like a Christmas tree.
In these scenarios, you should not attempt a 2020 ford explorer tpms reset while the tires are at low pressure. The system may not even allow a reset if the pressures are significantly below the factory-mandated thresholds.
Instead, simply ignore the light while on the trail. Once you return to pavement and use your portable compressor to air back up to street pressures, the light should turn off automatically after a few miles of driving. If it doesn’t, then you can perform the manual menu reset described earlier.
The Role of Temperature in Tire Pressure Fluctuations
As an expert technician, I often see customers come in during the first cold snap of autumn. Physics dictates that for every 10-degree drop in ambient temperature, your tires will lose approximately 1 PSI.
This “seasonal drop” is a frequent cause of the TPMS light. If you reset the light in the heat of the afternoon, it might come back on during a freezing morning. Always calibrate your 2020 ford explorer tpms reset when the tires are at their coldest point of the day to ensure a consistent baseline.
Using nitrogen instead of regular compressed air can mitigate these fluctuations slightly, but for most DIYers, simply staying on top of monthly pressure checks is the most cost-effective solution.
Frequently Asked Questions About 2020 ford explorer tpms reset
Can I reset the TPMS without a tool?
Yes, you can use the “pressure drop” method. Once the vehicle is in training mode, let air out of the tire for about 10-20 seconds until the horn honks, then move to the next tire. You will need to refill the tires afterward.
How long does the reset take to register?
While the training mode is instant, a menu-based 2020 ford explorer tpms reset might require you to drive the vehicle above 20 mph for at least 10 to 15 minutes before the light stays off permanently.
Will disconnecting the battery reset the TPMS light?
No, disconnecting the battery will not reset the TPMS. The sensor IDs are stored in non-volatile memory within the Body Control Module, so you must use the specific sequences mentioned above.
Why does my light come back on every morning?
This is likely due to “borderline” pressure. Your tires are just high enough to clear the light when warm, but the overnight cold drops the pressure just enough to trigger the sensor again. Add 2-3 extra PSI (staying under the max limit) to see if it stabilizes.
Final Thoughts for the DIY Mechanic
Mastering the 2020 ford explorer tpms reset is a rite of passage for any Ford owner who prefers to do their own maintenance. It saves you time, money, and the headache of staring at a warning light on your morning commute.
Remember that the TPMS is there for your protection. While it can be a nuisance, it is often the first line of defense against a catastrophic blowout or a slow leak caused by a nail or screw. Treat the system with respect, use the right tools, and always double-check your work with a manual gauge.
Stay safe on the road, keep those tires inflated, and enjoy the peace of mind that comes with a clear, functional dashboard!
