P0024 Subaru Code - Exhaust AVCS System 2 Range/Performance
Quick Answer
The Active Valve Control System (AVCS) varies camshaft timing by changing the camshaft phase angle depending on engine load in order to increase engine performance and efficiency and lower emission levels. Common causes include Low or Dirty Engine Oil, Faulty Oil Flow Control Solenoid, Oil Flow Control Solenoid harness is open or shorted. 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.
