EXHAUST GAS RECIRCULATION (EGR)
To lower oxides of nitrogen (NOx) exhaust gas emissions, an EGR system is used. EGR system introduces exhaust gases into intake system. Exhaust gases are noncombustible gases which, when combined with incoming air/fuel mixture, lower peak combustion chamber temperatures.
EGR Control (Esteem, Vitara & Grand Vitara)
EGR valve is controlled by PCM using a stepper motor attached to EGR valve. PCM uses signals from Camshaft Position (CMP) sensor, Engine Coolant Temperature (ECT) sensor, Mass Airflow (MAF) sensor and Vehicle Speed Sensor (VSS) to determine control of stepper motor.
