Detailed Description

This Walker oil pressure switch helps maintain early warning functionality in the lubrication system by alerting the ECU or driver when oil pressure falls outside the expected range. The switch is engineered for direct installation at the factory mounting point and connects to existing wiring without modification. Part number 256-1059 is used across many Hyundai and Kia platforms, including Hyundai Tucson, Hyundai Santa Fe, and Kia Sorento applications, making it a practical replacement when the original switch begins to trigger flickering oil lights, false warnings, or no signal during a true low-pressure condition. Walker 256-1059 is built to OE-style specifications so the electrical response and fit remain consistent with the original component.

What It Helps Address

• Oil warning light flickering or intermittent operation
• False low-oil-pressure alerts
• No signal from the pressure switch during actual low-pressure conditions
• Loss of reliable lubrication-system warning feedback
• Service needs during engine repair or rebuild work
