Buick Chevrolet Oil Pressure Sensor 12573107 12677836 OEM Replacement Part

This oil pressure sensor is a factory-specification component engineered as a direct replacement for the original part in certain Buick and Chevrolet vehicles. It is designed to restore accurate oil pressure monitoring, a critical function for your vehicle's engine management and warning light system. The sensor corresponds to several official part numbers, including 12573107, 12567323, 12562230, 12614969, 12616646, and 12677836, providing coverage for a range of models and engine types. Accurate oil pressure data helps protect your engine from damage caused by low oil pressure, making this a key maintenance item.

Features and Construction

This sensor is built to match the electrical and physical specifications of the original equipment manufacturer (OEM) parts it replaces. Its construction is tailored to withstand the temperature variations and vibrations found in a vehicle's engine bay.

Material and Build

The sensor uses materials compatible with engine oil and under-bonnet heat. The electrical connector is designed to match the vehicle's wiring harness for a secure connection that resists corrosion and ensures a reliable signal is sent to the vehicle's instrument cluster or engine control unit.

Size and Practical Fit

The external dimensions and thread specifications are manufactured to align precisely with the mounting point on the engine block for the applicable vehicles. This ensures a proper seal to prevent oil leaks and allows for correct threading without cross-threading during installation.

Uses and Placement

This component has a single, specific function: to monitor engine oil pressure. It is typically located on the engine block, near the oil filter housing or main oil gallery, where it can accurately sense pressure changes.

Event or Professional Use

The primary use case is the replacement of a failed or faulty oil pressure sensor. This is a common repair undertaken by professional mechanics and experienced DIY enthusiasts when a vehicle's oil pressure warning light illuminates, the gauge reads incorrectly, or a diagnostic code related to the sensor is logged.

Everyday Home Use

For the vehicle owner, installing a functioning sensor restores confidence in the dashboard warning system. It provides peace of mind that the low oil pressure warning light will activate correctly if a genuine problem arises, allowing for timely intervention to prevent potential engine damage.

Benefits and Buying Value

Choosing this specific sensor offers a practical solution focused on compatibility and restoring original function, rather than modifying performance.

Reuse and Low Maintenance

As a direct replacement part, it requires no modification or additional components for installation. Once fitted correctly, it functions as intended without any ongoing maintenance, simply becoming part of the vehicle's standard monitoring system for the lifespan of the component.

Why Choose This Product

This sensor is selected for its verified compatibility with the listed OEM part numbers and vehicle applications. It addresses the need for a correct, off-the-shelf component that matches the original design, facilitating a quicker and more reliable repair compared to universal parts that may require adaptors or yield inconsistent readings.
