Low Oil Pressure Indicator
WARNING: This page is about a different car, the 2019 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The IPC uses the oil pressure warning indicator request and engine rpm data to control the low oil pressure indicator. The engine oil pressure switch is hardwired to the PCM. The PCM provides the oil pressure warning indicator request and the engine rpm data to the GWM over the HS-CAN1. The GWM provides the oil pressure warning indicator request and engine rpm data to the IPC over the HS-CAN3.
