P0773 Mitsubishi Code - Reduction Solenoid Valve System
Quick Answer
Reduction solenoid valve is turned ON or OFF by the Transmission Control Module (TCM) in response to signals sent from the park/neutral position (PNP) switch, vehicle speed and Engine Control Module (ECM) (throttle opening). Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty Reduction Solenoid valve. 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.
