Tire Pressure Sensor: Testing and Inspection
TIRE PRESSURE SENSOR
NOTE: Tire pressure may increase from 14 to 41 kPa (2 to 6 psi) during normal driving conditions. Do NOT reduce this normal pressure build
up.
Check the tire pressure red telltale in the instrument cluster. If the red telltale is illuminating continuously, proceed as listed below. If the red telltale is
flashing on/off for 60 seconds, once every ten minutes, there is a system fault detected. Refer to the appropriate diagnostic information.
When diagnosing a tire pressure issue, always check air pressure in the tires first with a known accurate air gauge. Adjust air pressure as necessary to that
listed on the Tire Inflation Pressure Label (Placard) provided with the vehicle (usually applied to the driver's side B-pillar). After adjusting air pressure
in a tire, allow approximately two minutes for the message or red telltale to go out.
If air pressure in any tire is low, inspect all the tires for leaks. A water "dunk tank" or other water test may be used to check for a leak around the tire
assembly and sensor as long as any water at the valve core is removed once the procedure is completed. The water can be easily expelled from the core
area by pushing in on the core for several seconds, allowing escaping air to drive out any moisture. Reinflate the tire as necessary. Always make sure the
original valve stem cap is securely installed to keep moisture out of the sensor.
If the gauge-read pressure in the tires does not indicate a tire pressure issue, refer to the appropriate diagnostic information.
