What Does P0174 Mean on Your 2024 Chevrolet Colorado?
A P0174 code on your 2024 Chevrolet Colorado means the ECM detected a lean air-fuel mixture on Bank 2. The 2024 Colorado is a redesigned truck powered by a 2.7-liter turbocharged four-cylinder engine producing 237 horsepower in the standard tune or 310 hp in the high-output version. Since this is an inline four-cylinder with a single bank, P0174 may relate to sensor mapping, but the lean condition is real.
Your 2024 Colorado is under full factory warranty. Take it to the Chevrolet dealer for diagnosis and repair at no cost.
