Code P1198 Chevrolet Description
The P1198 code for Chevrolet vehicles specifically refers to an issue with the Exhaust Gas Temperature Sensor 5 Performance while the engine is running. This sensor is responsible for monitoring the temperature of the exhaust gases exiting the engine and relaying this information to the engine control module (ECM). The ECM uses this data to adjust fuel delivery and optimize the air-fuel mixture for efficient combustion and reduced emissions.
