Feedback Carburetor System: Description
The Closed Loop Emission control system is an electronically controlled system that is used on California I-Mark and P'UP engines. It monitors various engine/vehicle functions to control engine operation and lower exhaust emissions while maintaining good fuel economy and driveability.
The Electronic Control Module (ECM) is the brain of the system. The ECM controls the engine-related systems to constantly adjust engine operation to maintain good vehicle performance under all normal driving conditions. The system consists of the ECM, various engine sensors, a feedback carburetor and a catalytic converter.
