Let your engine's control system know when steering demand climbs with the Standard Ignition Power Steering Pressure Switch, part number PSS53. It fits many vehicles, among them the 1989-2004 Hyundai Sonata, 1992-1995 Hyundai Elantra and 2001-2004 Kia Optima. See the "Vehicles it fits" section for the full list and engine details.
The switch monitors pressure in the power steering system. When that pressure rises, as it commonly does during low-speed turns and parking maneuvers, the switch signals the engine's control system so the idle can be adjusted for the added pump load.
- Direct-fit OE replacement: Each switch is designed as a direct-fit OE replacement for easy installation on the listed applications.
- Controlled production: Standard Ignition is a global maker of automotive aftermarket products and maintains complete quality control through the manufacturing process.
- Built for tough conditions: Made from high-quality materials meant to stand up to extreme conditions.
- Tested: Every switch goes through extensive testing for reliability.
Signs the switch may need replacing include an idle that dips or stalls when you turn the wheel at low speed, or fluid seeping at the switch. These symptoms can have other causes, so diagnose the system before replacing parts. If a failed pressure switch is the cause, PSS53 replaces it.
