P14A6 Code - Charge Air Cooler Cooling Electric Water Pump
Quick Answer
The Charge Air Cooler (CAC) Cooling Electric Water Pump is an electric pump that circulates coolant through the intercooler system to lower the temperature of the air entering the engine. Common causes include Charge Air Cooler (CAC) coolant leakage, Charge Air Cooler coolant is mixed in air, Protection control is activated during pump idle running. 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.
