Tire Pressure Monitor Warning System

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. The 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.

Comments:

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?
 ANSWER: No. You either have a tire low air pressure, or a faulty sensor. Have the ABS computer scanned for codes for warning light.
