Oil Pressure Switch for 2009-2024 Chevrolet Silverado 1500 & More - Standard Ignition PS623

Keep an accurate eye on engine oil pressure with the Standard Ignition Engine Oil Pressure Switch PS623, a direct replacement engineered to deliver a highly accurate, timely oil pressure reading to your vehicle's data monitoring system. It is listed for many vehicles, among them the 2012-2023 Chevrolet Silverado 1500, 2014-2023 GMC Sierra 1500 and 2017-2022 Chevrolet Equinox. See the "Vehicles it fits" section for the full vehicle list and engine-specific fitment.

• Direct replacement: Designed for an OE fit, which keeps installation straightforward.
• Polyimide film diaphragm: High-temperature polyimide film diaphragms provide exceptional cycle durability and resist rupture and oil leakage. The unit is built to handle rapid pressure pulsations without component damage.
• Accurate signal: Manufactured and engineered to send a highly accurate and timely oil pressure reading to the vehicle's data monitoring system.
• 100% tested: Every unit is tested on vehicles and on automated equipment that activates the switch, checks for leaks and stresses the part to confirm it meets specification, even under demanding operating conditions.

A robust design and high-grade materials are intended to meet the stringent demands of today's service professional. The oil pressure switch monitors engine oil pressure and reports it so the vehicle can display an oil pressure warning or reading. Signs this part may need replacing include an oil pressure warning light that flickers or stays on with the oil at the correct level, an erratic or missing oil pressure reading, or oil seeping at the switch. Low oil pressure has other possible causes, so confirm actual oil pressure with a mechanical gauge before replacing the switch. If a failed switch is the cause, the PS623 replaces it.
