Tyre pressure sensor (754)
|
The pressure sensor is located in the tyre valve.
The sensor transmits tyre pressure information to the control module which in turn informs the driver if the air pressure in a tyre is too low.
The tyre pressure sensor is an integrated sensor, transmitter, battery and valve. It comprises a plastic housing, with an electronic unit, which is joined to an aluminium housing with a valve. On the valve are a tapered seal and a crown nut, which is used to fit the valve into the corner of the wheel. The sensor weighs approximately 38 g.
There is a 3V (500 mAh) lithium battery in the sensor which is activated by a ball switch in the electronic unit. The battery is not replaceable.
