Detailed Description

Walker Products 256-1124 is engineered for vehicles that rely on a single oil pressure switch input to trigger the warning lamp or communicate pressure status to the engine control system. This part is manufactured to OE specifications so the thread engagement, terminal layout, and electrical response match the original component. For drivers searching for a Hyundai Elantra oil pressure switch or a Kia Niro engine oil pressure switch, this Walker replacement provides the correct fitment and signal behavior for the listed applications.

The switch uses a blade pin terminal with a female connector and male terminal interface, and its metal and plastic construction is selected for high-temperature, oil-exposed engine environments. Walker 256-1124 threads into the factory location without modification and connects to existing wiring, making it a practical choice for scheduled maintenance, drivability repair, or engine rebuild work on compatible Hyundai Elantra, Hyundai Ioniq, and Kia Niro models.

Common Issues This Part Can Address

• Oil warning light flickering during normal driving
• False low-oil-pressure warnings on the dash
• No warning signal when actual oil pressure drops
• Intermittent oil pressure switch electrical signal
• Faults related to a worn or failed engine oil pressure switch

Installation Notes and Tips

Install the switch in the original factory location, typically on the engine block or oil filter housing, and verify the connector style before installation. Confirm the thread size and terminal configuration against the removed part to ensure proper fit. For best results, inspect the wiring connector and surrounding oil passages for damage or contamination before reconnecting the harness. Walker 256-1124 is a direct OE-style replacement, so no wiring changes are required on the listed applications.

Quality Assurance

Walker Products manufactures this oil pressure switch to OE replacement standards for pressure threshold, fit, and electrical response. The part is built for consistent operation in engine environments where heat and oil exposure are constant, helping maintain reliable pressure monitoring on covered Hyundai and Kia vehicles.
