What is TPMS on Ford Expedition?

TPMS on Ford Expedition
The TPMS (Tire Pressure Monitoring System) on the Ford Expedition is a system that monitors the tire pressure in each of the vehicle’s tires. It uses TPMS sensors that are installed in the wheels to detect low tire pressure. If one or more tires indicate low pressure, the TPMS sensors will transfer this information to the vehicle’s ECU (Engine Control Unit). This can be indicated by a warning light on the dashboard, either as a low-line TPMS system or by displaying the tire pressure for each tire on the dash (high-line TPMS system) .
The Ford Expedition uses a direct TPMS system, which means that the TPMS sensors are installed in the wheel itself . This is different from an indirect TPMS system, which uses the ABS wheel speed sensors to monitor the rolling radius of the wheel and tire assemblies.
When one or more TPMS sensors are replaced in a Ford Expedition, it is recommended to perform a TPMS relearn procedure. This relearn procedure writes the sensor IDs to the vehicle’s ECU, allowing it to recognize the new sensors and turn off the TPMS warning light.
It’s worth noting that there are aftermarket devices available, such as TPMS bypass sensors emulators, that can be used to bypass or disable the TPMS system. However, it’s important to check the compatibility of these devices with your specific vehicle before purchasing or using them.

Does TPMS mean flat tire?

What Does the TPMS Light Mean? The tire pressure monitoring system light, shaped like a horseshoe with an exclamation point in the middle, normally means that you have a tire with low pressure. If you see the TPMS light illuminated, it’s best to stop driving and check the air pressure in each tire.

Why is my TPMS light on but tires are fine?

The causes can be a malfunction, or the weather changes. Other reasons why your TPMS light may still be blinking is because your tire may be damaged, or you might have gotten a recent tire replacement. Overall, the reasons can be vast, which is why it is best to take your car to a technician for professional diagnosis.

How do you reset the TPMS on a Ford Expedition?

When the vehicle is off, turn the key to the “On” position, but don’t start the car. Hold down the TPMS reset button until the light blinks three times, then let go. Start the car and give the vehicle about 20 minutes for the sensor to reset. Generally, you’ll find the reset button under the steering wheel.

Can overinflated tires cause TPMS light to come on?

If your tires are under- or over-inflated, the TPMS activates a warning light on your dashboard. When the light is steady, it means you need to have your tire pressure checked. When the light is flashing, it means you need to have your TPMS checked.

How do I know if my tire pressure sensor is messed up?

If you notice that your tires have low air pressure and there was no warning from the system, it is most likely due to a failure of a TPMS sensor. Using a tire pressure gauge indicates a problem with the sensor or a tire. Another noticeable side effect is when steering becomes tight.

Why would my TPMS light be on?

When the TPMS light comes on – and stays on – at least one of your tires is at a low pressure level. Check the pressure of all of the tires with a gauge and determine the cause of pressure loss and add air or service the tire(s) as appropriate.

Can I reset my TPMS myself?

Drive at or above 50 mph to reset the sensor for 10 minutes. This causes your sensor to reset the next time you turn on your car. With the vehicle off, turn the key to the “On” position, but do not start the car. Hold the TPMS reset button until the tire pressure light blinks three times, then release it.

What does tire pressure sensor fault mean on a Ford Expedition?

What does a flashing tire pressure light mean? This may indicate that the tire pressure sensors need replacement batteries, or that there is an issue with one of the sensors in general.

Where is the TPMS reset button?

Set the parking brake. Look for a button to the left of the steering column labeled with the TPMS icon if it’s there push and hold it until the TPMS indicator in the instrument panel blinks twice.

Is it OK to drive with TPMS light on?

As we mentioned earlier, a tire pressure light is a warning, not a command, so you don’t need to pull over immediately if you see it come on. However, driving on underinflated tires can be dangerous and can cause a variety of problems, including poor handling, reduced fuel efficiency, and increased tire wear.
