A quick glance at your dashboard might reveal a flashing tire pressure warning light, specifically concerning your 2020 Ford Explorer’s tire pressure sensor system. This guide will help you understand why it’s on, how to check your tires, and what to do next to ensure safe driving.
Your 2020 Ford Explorer relies on a sophisticated Tire Pressure Monitoring System (TPMS) to alert you to underinflated tires, a critical safety feature. When the 2020 Ford Explorer tire pressure sensor system detects a problem, a warning light illuminates on your dashboard. This article will demystify this system, guide you through common issues, and provide practical steps for maintenance and troubleshooting, empowering you to keep your Explorer safe and performing at its best.
Understanding Your 2020 Ford Explorer Tire Pressure Sensor System
The Tire Pressure Monitoring System (TPMS) on your 2020 Ford Explorer is designed with your safety in mind. It uses sensors mounted inside each wheel to continuously monitor the air pressure within your tires. This data is then transmitted wirelessly to your vehicle’s onboard computer.
If the system detects that one or more tires are significantly underinflated – often by 25% or more below the recommended pressure – the TPMS warning light will illuminate on your instrument cluster. This is your vehicle’s way of telling you that your tires could be unsafe, impacting handling, braking, and fuel efficiency. Understanding this system is the first step to addressing any issues.
Why the 2020 Ford Explorer Tire Pressure Sensor Light Might Be On
Several factors can trigger the TPMS warning light, and it’s not always about a puncture. Often, simple changes in temperature can affect tire pressure. For instance, colder weather causes air to contract, leading to a drop in pressure.
Other common culprits include:
- Low Tire Pressure: This is the most direct reason. Underinflation can be caused by slow leaks, punctures, or simply losing air over time.
- Temperature Fluctuations: As mentioned, significant temperature drops can lower tire pressure enough to activate the sensor.
- Recent Tire Inflation: If you’ve recently inflated your tires, the system may need a reset or recalibration.
- Spare Tire: Some TPMS systems, including those on certain 2020 Ford Explorer models, monitor the spare tire as well. If the spare is underinflated, the light can come on.
- Faulty Sensor: Over time, the internal battery in a TPMS sensor can die, or the sensor itself can malfunction.
- TPMS Receiver/Module Issue: While less common, problems with the vehicle’s TPMS receiver or control module can also cause false warnings.
Step-by-Step: Checking Your Tire Pressure and the 2020 Ford Explorer Tire Pressure Sensor
Before assuming the worst, a simple check of your tire pressure is always the first and most crucial step.
1. Locate Your Vehicle’s Recommended Tire Pressure
You’ll find the recommended tire pressure for your 2020 Ford Explorer on a sticker located on the driver’s side doorjamb. It will also be listed in your owner’s manual. Note that this is different from the maximum pressure listed on the tire sidewall.
2. Gather Your Tools
You’ll need a reliable tire pressure gauge. Digital gauges are often preferred for their accuracy and ease of reading.
3. Check Tire Pressure When Tires Are Cold
It’s essential to check your tire pressure when the tires are “cold,” meaning the vehicle hasn’t been driven for at least three hours, or has been driven less than a mile at moderate speed. Driving heats up the tires, increasing the air pressure and giving an inaccurate reading.
4. Remove Valve Stem Caps and Measure Pressure
Unscrew the cap from one tire’s valve stem. Firmly press the tire pressure gauge onto the valve stem. The gauge will display the current pressure.
5. Compare and Adjust
Compare the reading to your vehicle’s recommended pressure. If it’s low, use an air compressor to add air until you reach the correct PSI. If it’s high (which is rare with the TPMS light on, but possible), release air by pressing the small pin in the center of the valve stem with the gauge’s nub.
6. Repeat for All Tires (Including the Spare)
Don’t forget to check all four main tires and, if applicable, your spare tire. Once all tires are at the correct pressure, screw the valve stem caps back on tightly.
Addressing a Persistent 2020 Ford Explorer Tire Pressure Sensor Warning Light
If you’ve correctly inflated all your tires and the TPMS light remains illuminated, it’s time to investigate further.
Resetting the TPMS System
Some vehicles require a manual reset after adjusting tire pressures. While your 2020 Ford Explorer may have an automatic reset function, a manual reset can sometimes clear phantom warnings.
- Check Your Owner’s Manual: The exact procedure can vary slightly. Typically, you’ll find a TPMS reset button or a menu option within your infotainment system or instrument cluster settings.
- Common Reset Procedure: Often, you’ll need to turn the ignition key to the “ON” or “RUN” position (without starting the engine), then press and hold the TPMS reset button for a few seconds until the light flashes or goes out. You might need to repeat this.
When to Suspect a Faulty Sensor or Component
If the light still persists after resetting and confirming correct tire pressures, a faulty component is likely the cause.
- Sensor Malfunction: TPMS sensors have a lifespan, and their internal batteries eventually deplete. A dead sensor won’t transmit data, and the system will alert you.
- Sensor Damage: Sensors can be damaged during tire changes, from road debris, or through corrosion.
- Relearning Procedure: After replacing a TPMS sensor, the new sensor needs to be “relearned” by the vehicle’s computer. This often requires specialized diagnostic tools.
DIY vs. Professional Help for Your 2020 Ford Explorer Tire Pressure Sensor
While checking tire pressure and attempting a reset can be done by any owner, more complex TPMS issues often require professional intervention.
DIY Tasks You Can Handle
- Checking and adjusting tire pressure: This is straightforward and essential for safety.
- Locating the TPMS reset function: Your owner’s manual is your best friend here.
- Visual inspection of tires: Look for obvious damage, nails, or foreign objects.
When to Visit a Mechanic or Tire Shop
- Persistent Warning Light: If the light stays on after proper inflation and reset.
- Sensor Replacement: Replacing a TPMS sensor is a specialized job. It involves removing the tire from the rim, so it’s best left to professionals.
- TPMS Diagnostics: Technicians have tools to read TPMS codes, identify faulty sensors, and perform the necessary relearning procedures.
- Battery Replacement (if applicable): Some older TPMS systems allowed for battery replacement, but most modern sensors are sealed units that require full replacement.
Understanding TPMS Sensor Replacement and Calibration
Replacing a 2020 Ford Explorer tire pressure sensor is a precise job.
The Process
- Tire Removal: The tire must be dismounted from the wheel.
- Sensor Access: The TPMS sensor is typically held in place by a small nut or screw on the inside of the valve stem.
