C2023 Subaru Code - Tire 3 Air Pressure Decrease
Quick Answer
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. Common causes include Tire pressure not to factory specifications, Faulty Tire Pressure Transmitter, Faulty Tire Pressure Monitor System (TPMS) Control Module. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
