Buick and Chevrolet Oil Pressure Sensor: Direct Replacement for Models 12573107 12567323 12562230

This oil pressure sensor is a factory-style replacement component designed for Buick and Chevrolet vehicles. It addresses the need for a reliable part to monitor engine oil pressure, a critical parameter for vehicle health and performance. When the original sensor fails, providing inaccurate readings or triggering warning lights, this unit offers a straightforward solution to restore proper system function. Its compatibility is indicated by a range of part numbers, including 12573107, 12567323, 12562230, 12614969, and 12616646, suggesting it fits multiple GM vehicle platforms and engine types. Installation typically involves locating the original sensor on the engine block, disconnecting the electrical plug, and swapping the units, making it a common repair for both professional mechanics and experienced DIY enthusiasts.

Features and Construction

This sensor is built to serve as an integral part of your vehicle's engine management system, monitoring the pressure of the circulating oil.

Material and Build

The sensor is constructed from materials engineered to withstand the engine bay environment, including exposure to heat, vibration, and engine oil. Its housing is designed to seal against the engine block to prevent oil leaks. The internal mechanism converts oil pressure into an electrical signal that is sent to the vehicle's instrument cluster or ECU. The specific metals, seals, and electronic components used are typical of original equipment manufacturer (OEM) specifications for this type of automotive sensor, ensuring it can handle the operational demands placed upon it.

Size and Practical Fit

The sensor is designed as a direct physical replacement for the original unit in compatible vehicles. Its thread size, port configuration, and electrical connector are made to match the OEM part, allowing for a straightforward install without modification. The exact physical dimensions—such as overall height, thread pitch, and connector type—are determined by the specific part numbers it replaces (12573107, etc.). Users should verify the fitment against their vehicle's existing sensor or consult a fitment guide before purchase to ensure correct application.

Uses and Placement

This component has a single, defined purpose within the vehicle's lubrication system, and its placement is fixed by the vehicle's design.

Event or Professional Use

For professional automotive technicians, this sensor is a standard service part used during routine maintenance or fault diagnosis. It is commonly fitted when a diagnostic scan tool identifies a fault code related to the oil pressure sensor circuit, or when a customer reports an erratic oil pressure gauge or warning light. Garages and parts suppliers stock such sensors to fulfil these common repair needs efficiently, keeping vehicle downtime to a minimum.

Everyday Home Use

For the home mechanic, replacing a faulty oil pressure sensor can be a manageable project that resolves a persistent warning light and restores confidence in the vehicle's gauges. It is a targeted repair that addresses a specific component failure. The job typically requires basic mechanical tools, some knowledge of your engine layout, and care to avoid damaging the connector or creating an oil leak. Successfully completing this repair can be a cost-effective alternative to a garage visit.

Benefits and Buying Value

The value of this product lies in its specificity and function, restoring a key monitoring system in your vehicle.

Reuse and Low Maintenance

Once installed, the sensor requires no ongoing maintenance. It is a fit-and-forget component that will function for the lifespan of the vehicle or until it succumbs to normal wear. Its value is realised through the restored functionality of the oil pressure warning system, which is a critical part of preventive maintenance, alerting the driver to potentially serious low oil pressure conditions before they cause engine damage.

Why Choose This Product

This sensor is chosen for its confirmed compatibility with a list of specific GM part numbers and its application to popular Buick and Chevrolet models. It provides a direct solution to a common point of failure. The alternative for a driver is often a more expensive OEM dealer part or a generic unit of unverified fitment. This product sits in the middle, offering a likely correct fit based on its listed part numbers without the premium brand-name cost, assuming those numbers match the original sensor on your vehicle.
