Standard Ignition Engine Oil Pressure Switch P/N:PS623
Standard Motor Products
Keep an eye on your engine's lubrication with the Standard Ignition PS771 Engine Oil Pressure Switch. It is engineered to send an accurate, timely oil pressure reading to the vehicle's data monitoring system. It fits many vehicles, among them the 2017-2022 Jeep Cherokee, 2017-2022 Jeep Compass and 2018-2022 Ram ProMaster City. See the "Vehicles it fits" section for the full list and engine details. As a direct replacement, it is built for an OE fit so installation is straightforward.
The oil pressure switch senses engine oil pressure and reports it so the vehicle can warn the driver when pressure drops. Signs this switch may need replacing include a flickering or constantly lit oil pressure warning light, erratic gauge readings, or oil seeping from the switch body. Because genuinely low oil pressure can cause the same warning, verify actual pressure before replacing. If a failed switch is the cause, the PS771 replaces it.

What are signs an oil pressure switch may need replacing?
Look for a flickering or constantly lit oil pressure light, erratic gauge readings, or oil seeping from the switch. Verify actual oil pressure first, since low pressure also triggers the warning.
