Code C2221 Subaru Description

The Tire Pressure Monitor (TPM) system checks the tire pressures of all 4 road wheels when the vehicle is driven at speeds above 25 mph (40 km/h), and warns in the event of a loss of pressure by means of a low tire pressure warning light. A sensor installed in each wheel will indicate when tire pressure is severely low. The TPM system will activate only when the vehicle is driven. The Tire Pressure Monitor System (TPMS) Control Module monitors the tire pressure at each wheel. The TPMS Control Module sets the OBDII code when the tire pressure signal is not to factory specifications.
