Walker 256-1055 Engine Oil Pressure Switch

Engine Oil Pressure Switch Overview

Walker 256-1055 is an OE replacement engine oil pressure switch built to monitor lubrication pressure and send a warning signal when pressure drops below safe limits. It is a direct-fit solution for a wide range of applications, including Hyundai Elantra, Kia Rio, and Chrysler Sebring models.

Key Features

• OE replacement design for factory-style oil pressure monitoring
• Steel construction with a metal finish for engine-bay durability
• Spade terminal with one male connector and one male terminal
• Matches OE specifications for pressure threshold, thread size, terminal type, and electrical response
• Walker 256-1055 supports early warning functionality in the lubrication system

Detailed Description

This Walker oil pressure switch is engineered to provide accurate pressure signaling to the ECU or dashboard warning circuit when oil pressure falls outside the normal range. The switch threads into the factory location and connects to existing wiring without modification, making it a practical replacement for vehicles that show flickering oil lights, false warnings, or no signal during a true low-pressure condition. Part number 256-1055 is used across multiple makes and models, including Hyundai Sonata, Kia Sportage, and Ford Escort applications.

Walker Products manufactures this switch to OE-style specifications so the electrical response and physical fit align with the original component. The steel body and oil-resistant, high-temperature construction help it withstand prolonged engine exposure while maintaining consistent operation. If you are replacing a failed oil pressure sender on a Hyundai Elantra, Kia Rio, or similar application, Walker 256-1055 provides a direct-fit service part for restoring warning-system function.

What It Is Used For

• Restoring oil pressure warning light operation
• Correcting false or intermittent oil pressure alerts
• Replacing a switch that no longer signals low pressure
• Addressing drivability concerns tied to lubrication-system monitoring
• Supporting engine protection after oil-pressure-related faults

Installation Notes and Tips

Verify thread size, terminal style, and connector type before installation. This switch is designed to thread into the factory location and connect to existing wiring. Confirm the vehicle application against the fitment list for your exact year, make, and model before ordering Walker 256-1055.

Quality Assurance

Walker Products builds this oil pressure switch to match OE specifications for pressure thresholds, terminal configuration, and electrical response. The design uses high-temperature and oil-resistant materials for consistent performance in engine environments.
