How does Ford TPMS work?

How Ford TPMS Works
Ford’s Tire Pressure Monitoring Systems (TPMS) can be direct or indirect, and all 2007 models have TPMS standard. From 2006-2009, Ford used banded sensors that are mounted in the center of the rim. In 2010, Ford reverted to the valve stem mounted sensors. These systems are straightforward and use common procedures for most models. The TPMS system detects differences in inflation pressures in one or more tires. The system uses the ABS wheel speed sensors to monitor the rolling radius of the wheel and tire assemblies. Ford systems use the unique ID numbers of the sensors that have to be registered along with the vehicle.
There are two different types of TPMS being used today: Direct TPMS and Indirect TPMS. Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. When air pressure drops 25% below the manufacturer’s recommended level, the sensor transmits that information to the car’s computer system and triggers the dashboard indicator light. Indirect TPMS works with the car’s Antilock Braking Systems (ABS) wheel speed sensors.
In summary, Ford’s TPMS works by monitoring the tire pressure using sensors and alerting the driver when there is a drop in pressure, ensuring that the tires are within their optimum range for safety and performance.

How do TPMS sensors transmit?

These sensors constantly monitor tire pressure and relay this information to the vehicle’s onboard computer. So, how do TPMS sensors communicate with the rest of the system? They typically use wireless technology, such as RF signals, to transmit the collected data.

How is the TPMS sensor working?

Based on the rate of revolution of each wheel, the computer can interpret the relative size of the tires on your vehicle. When a wheel starts spinning faster than expected, the computer calculates that the tire is underinflated and alert the driver accordingly.

Do new Ford TPMS sensors need to be programmed?

Every replacement TPMS sensor must be “relearned” to the vehicle following the prescribed OE relearn procedure, regardless of whether it is an OE or aftermarket sensor.

Do Ford TPMS sensors have batteries?

Most TPMS sensors run on batteries that are built into the sensor and these batteries are not replaceable. The life expectancy of the lithium ion batteries in a TPMS sensor is anywhere from 5-10 years.

Can you reset Ford TPMS without tool?

Resetting Your Tire Pressure Light
Attempt to reset the TPMS sensor by driving at least 50 mph for 10 minutes. The next time you turn the car on, the light should be off.

Is Ford TPMS direct or indirect?

direct
After the TREAD Act was mandated in 2007, all vehicles manufactured in the United States beginning in 2008, must be installed with direct or indirect TPMS systems. The Ford Focus uses a direct TPMS system, which means TPMS sensors are installed in the wheel.

What type of TPMS does Ford use?

Ford TPMS types and Fitment
The manufacturers of the Ford TPMS are Schrader Electronics, VDO and Lear. VDO and Lear manufactured the banded sensor whilst Schrader manufacture the valve stem TPMS.

Can you just replace the battery in a TPMS sensor?

The potting compound is likely the reason most TPMS sensors don’t have replaceable batteries. Potting compound prevents vibration, strain, and shock from damaging electronics. The sensor lives in a wheel that spins fast and rolls over potholes. The potting compound is what keeps it from failing quickly.

How do TPMS sensors know which wheel?

Each tire pressure sensor sends out a radio frequency signal. In this signal is tire data and the sensor’s unique ID code. Each sensor position is matched or “trained” to the control module.

How does Ford tire pressure monitor work?

Each wheel is fitted with a sensor that, when your vehicle is on, reports the tyre pressure to the cars computer. If one or more of your tyres has low pressure, the system will display an indicator light on the dashboard. You will then need to check the pressures of each tyre.
