Code P024D Description

The P024D diagnostic trouble code (DTC) indicates a problem with the Charge Air Cooler (CAC) Bypass Position Sensor 'A' circuit's range or performance. The Charge Air Cooler is a component of the vehicle's turbocharged or supercharged engine system that cools down the compressed air before it enters the engine. The bypass position sensor is responsible for monitoring the position of the bypass valve, which regulates the flow of air through the CAC.
