Keep an accurate eye on engine oil pressure with the Standard Ignition Engine Oil Pressure Switch PS623, a direct-fit replacement that drops in like the original for a huge GM-based lineup — including the 2012-2023 Chevrolet Camaro, 2012-2023 Chevrolet Silverado 1500, 2015-2023 Chevrolet Suburban, 2016-2019 Cadillac ATS, 2009-2023 GMC Yukon, and 2016-2019 Buick Cascada. Fitment spans 93 applications across Buick, Cadillac, Chevrolet, GMC, Hummer, MG, and Pontiac, so see the Buyer's Guide tab for the full list and the correct engine for your vehicle.
This switch reads engine oil pressure and reports it to the vehicle's data monitoring system, feeding the gauge or warning light. If a failed oil pressure switch is the cause of an erratic gauge, a false low-oil-pressure light, or a small leak at the sensor port, replacing it with PS623 addresses that faulty component.
- Direct replacement: engineered for OE fit to ease installation.
- Polyimide film diaphragm: high-temperature material designed for cycle durability and resistance to rupture and oil leakage, and built to handle rapid pressure pulsations without component damage.
- Accurate readings: engineered to deliver a highly accurate, timely oil pressure signal to the data monitoring system.
- 100% tested: checked on vehicles and with automated equipment that activates the switch, checks for leaks, and stresses the part for specification compliance.
