The first generation of TPMS sensors that are integral with the valve stem can suffer from corrosion. [12] [13] Metallic valve caps can become seized to their valve stems due to galvanic corrosion and efforts to remove these caps can break the stem, destroying the sensor. A similar fate may befall aftermarket brass valve cores installed in ...
direct TPM sensor fitted in valve system, manufacturer VDO. In most current designs of direct TPMS, a small electronic assembly which is rugged enough to be mounted inside a tire, measures the pressure using a microelectromechanical system (MEMS) [1] pressure sensor and then transmits this and other information to one or more vehicle receivers. [1]
The dustcap is internally threaded and is secured by screwing it onto the end of the stem. To prevent corrosion due to electrolysis and malfunction of the electronics in a direct TPMS and avoid costly repairs, metal valve caps without insulating plastic linings should not be used on direct-TPMS-equipped tire valve stems.

Many modern cars now come with built-in tire pressure sensors that allow all four tire pressures to be read simultaneously from inside the car. Before 2005, most on-board tire-pressure monitoring systems (TPMS) used indirect pressure monitoring. The anti-lock brake sensors detect one tire rotating faster than the rest and indicate a low tire ...
Other features included side-intrusion door beams, security approach lamps, SecuriLock with smart key and engine immobilizer, BeltMinder, three-point safety belts for all rows of seating, post-crash fuel pump shut-off, tire pressure monitoring system (TPMS) and four-wheel, four-sensor, four-channel anti-lock braking system (ABS) with electronic ...

In the tire factory, the tire and wheel are mounted on a balancing machine test wheel, the assembly is rotated at 100 RPM (10 to 15 mph with recent high sensitivity sensors) or higher, 300 RPM (55 to 60 mph with typical low sensitivity sensors), and forces of unbalance are measured by sensors. [1]
Capacitive Sensors generate a dielectric field between the tire and sensor. As the distance between the tire and the sensor varies, the voltage and/or current properties of the dielectric field change. Analog circuitry is employed to measure the field changes and record the run-out waveform. Capacitive sensors have a larger area-of-interest, on ...
