Code P023A Description

The diagnostic trouble code P023A refers to an issue with the charge air cooler coolant pump control circuit being open. In modern turbocharged vehicles, the charge air cooler, also known as an intercooler, cools down the compressed air coming from the turbocharger before it enters the engine. The charge air cooler coolant pump is responsible for circulating coolant through the intercooler to effectively cool down the intake air.
