Service Tire Pressure Monitor System.

The tire pressure monitor system in todays cars use a radio frequency (RF) transmitter
Tire Pressure Sensor ) in each wheel valve stem to relay pressure information to the
module. The
Service Tire Pressure Monitor System light / warning means there is
a problem in the system, not a low tire.
Low tire pressure warning would come on for a low tire.

The system would need to be scanned for codes if the
service monitor system warning comes on.

After a
tire rotation, the tire positions need to be relearned in order for the system to
tell you which tire is low. A special procedure and tool is need to do this.
my Saturn Vue is out of
alignment, would that cause my low tire sensor to be on
and would it cause my traction control light to stay on?
No. You either have a tire low air pressure, or a
faulty sensor. Have the ABS computer scanned
for codes for warning light.
