Standard Ignition Engine Oil Pressure Switch P/N:PS686
Keep oil pressure information flowing to your engine's monitoring system with the Standard Ignition switch PS660, an engine oil pressure switch designed as a direct replacement for an OE fit and straightforward installation. It fits many vehicles, among them the 2014-2019 Chevrolet Impala and 2013-2019 Chevrolet Malibu. See the Buyer's Guide tab for the full list of Chevrolet, Buick, Cadillac, GMC and Hummer applications and engine details.
The switch monitors engine oil pressure and signals the vehicle so a pressure problem can be flagged on the dash. Signs it may need replacing include an oil pressure warning light that flickers or stays on, an erratic gauge reading, or oil seeping at the switch. Confirm actual oil pressure before replacing it, because a warning can also point to a genuine engine problem.
