Stepper motor connector
The EGR stepper motor is driven by the Powertrain Control Module (PCM) using pulse-width modulated signals.
The use of the EGR stepper motor ensures a high level of precision for the exhaust gas recirculation system.
The EGR stepper motor is mounted directly behind the cylinder head and is connected via a throughflow duct to the exhaust manifold on the opposite side of the cylinder head.
