Freightliner engine code 545 typically indicates a fault related to the engine's turbocharger or related components. This code may suggest issues such as a turbo underboost, overboost, or problems with the wastegate. It's important to diagnose the specific cause using diagnostic tools to ensure proper repairs and maintenance of the engine system. Always refer to the manufacturer's service manual for precise definitions and troubleshooting steps.
