Transmission Fluid Cooler Coolant Control Valve (If Equipped)
WARNING: This page is about a different car, the 2021 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
The transmission fluid cooler coolant control valve is an electrically controlled solenoid to redirect the flow of engine coolant. This electrically controllable valve is normally closed when not energized. The valve receives a fused 12V B+ supply when the ignition is in the run or start position and is grounded by the PCM via a low side driver. The PCM monitors the solenoid and circuits for electrical faults and sets an appropriate DTC.
