Code P24A5 Cadillac Description

The P24A5 diagnostic trouble code for Cadillac vehicles indicates a problem with the Exhaust Gas Recirculation (EGR) Cooler Bypass Control being stuck on Bank 1. The EGR system is responsible for reducing emissions by recirculating a portion of the exhaust gases back into the engine cylinders for combustion. The EGR cooler helps to lower the temperature of the recirculated exhaust gases before they are reintroduced into the engine, improving efficiency and reducing emissions.
