The EGR system is controlled by a pulse width modulation (PWM) signal from the engine control module (ECM). The system comprises an EGR valve and a gas transfer pipe.
The EGR valve comprises a 4 pole stepper motor with an integral cooler unit which is mounted on the side of the induction elbow. The EGR valve is cooled by the return coolant flow from the electric throttle.
The EGR valve is connected to the LH exhaust manifold via the gas transfer pipe.
