In either case, the pressure sensor is covered by the tire and is
not visible unless the tire is removed. Care must be taken when
changing the tire to avoid damaging the sensor. It is recommended
that you always have your tires serviced by an authorized dealer.
The tire pressure should be checked periodically (at least monthly) using
an accurate tire gauge, refer to Inflating your tires in this chapter.
How to identify which type of pressure sensor is on your vehicle
The wheel could have either type of pressure sensor depending on the
appearance of the valve stem:
• Rubber valve stem with snap-in
sensor- the valve stem has a
rubber seal (1) and an extra
brass shoulder, larger in diameter
and with no treads, that can be
seen when the cap is removed.
• Rubber valve stem with banded
sensor- the valve stem has a
rubber seal (1) with brass of a
uniform diameter all the way
down to the seal.
