Subaru Impreza WRX Tire Pressure Light in Thornton, CO

On the Subaru Impreza WRX, the tire pressure light—a horseshoe-shaped tire outline with an exclamation point—means one or more monitored tires is at least 25 percent below the pressure on the driver's door-jamb placard when the light stays on, while a light that flashes for about a minute at startup and then remains illuminated indicates a tire-pressure monitoring system fault, making a pressure and sensor check the right next step for identifying low air, a puncture, a leaking valve stem, or a sensor battery issue across all model years.

Mike Shaw Subaru in Thornton, CO, provides tire pressure light service for the Subaru Impreza WRX, checking the tires and monitoring system so the driver can understand why the warning appeared and arrange the appropriate inspection.

What the tire pressure light means on a Subaru Impreza WRX

The warning appears as a horseshoe-shaped tire outline with an exclamation point inside. When it stays steadily lit, one or more monitored tires is at least 25 percent below the placard pressure on the driver's door jamb. This can happen after a cold night because tire pressure drops about one psi for every ten degrees. An underinflated tire wears faster and runs hotter, so the pressure should be set at the next stop.

If the light stays on even though the tires look fully inflated, the vehicle needs a pressure check and inspection rather than relying on appearance alone. If it flashes for about a minute at startup and then stays lit, the monitoring system itself has a fault, usually involving a sensor whose battery has run down.

What the diagnosis covers at Mike Shaw Subaru

The service begins with a pressure check of every monitored tire against the placard on the driver's door jamb. Each tire-pressure sensor's signal and battery status are scanned to distinguish a tire-pressure concern from a monitoring-system concern.

The inspection also checks for punctures and leaking valve stems. After any sensor or tire work, the system is relearned so the vehicle can recognize the serviced components. This process separates a tire that needs air or repair from a sensor that needs replacement. Drivers can schedule service at Mike Shaw Subaru for a complete tire pressure light diagnosis.
