Code P245A Cadillac Description

The P245A diagnostic trouble code (DTC) in Cadillac vehicles refers to an issue with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control Circuit. The EGR system plays a crucial role in reducing harmful emissions by recirculating a portion of the exhaust gases back into the combustion chamber for a second burn. The EGR Cooler Bypass Control Circuit is responsible for regulating the flow of exhaust gases through the EGR cooler to control engine temperature and emissions.
