P0489 Mitsubishi Code - EGR Stepper Motor Circuit Malfunction Ground Short
Quick Answer
The Engine Control Module (ECM) monitors the Exhaust Gas Recirculation Throttle Control Circuit. Common causes include Faulty Exhaust Gas Recirculation (EGR) Solenoid, Exhaust Gas Recirculation (EGR) Solenoid harness is open or shorted, Exhaust Gas Recirculation (EGR) Solenoid circuit poor electrical connection. 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.
