What Does P0174 Mean on Your 2022 Chevrolet Camaro?
A P0174 code on your 2022 Chevrolet Camaro means the ECM detected a lean air-fuel mixture on Bank 2. The 2022 Camaro offers a 2.0-liter turbo four-cylinder (275 hp), a 3.6-liter V6 (335 hp), or a 6.2-liter V8 (455 hp in the SS, 650 hp in the ZL1). On V6 and V8 models, Bank 2 is a distinct cylinder bank. On the turbo four-cylinder, Bank 2 designation may relate to sensor mapping.
