Code P0765 KIA Description

The P0765 diagnostic trouble code for KIA vehicles specifically relates to the Overdrive Solenoid Valve System. In automatic transmissions, the overdrive solenoid valve is responsible for controlling the flow of transmission fluid to engage or disengage the overdrive gear. Overdrive is an extra gear in the transmission that allows the engine to run at a lower RPM, improving fuel efficiency and reducing wear on the engine.
