WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2019 Lincoln Navigator, 2019 Lincoln Nautilus, 2019 Lincoln MKZ, 2019 Lincoln MKT, and 2019 Lincoln MKC. However, it is still accessible from the selected car via links, so may be relevant.
The turbocharger wastegate motor is attached to the turbocharger and allows the PCM to control the turbocharger wastegate position. The turbocharger wastegate motor controls the turbocharger wastegate linkage position to control the boost pressure limit. During driving conditions, the PCM controls the turbocharger wastegate motor position with positive and negative voltage circuits, to change the position of the turbocharger wastegate to increase or decrease the boost pressure to the desired value. The PCM monitors the turbocharger wastegate position sensor signal for feedback on the wastegate motor performance, and to detect a stuck wastegate. The turbocharger wastegate position sensor is integral to the turbocharger wastegate motor.
