Direct Replacement Oil Pressure Sensor for Buick and Chevrolet Models

This oil pressure sensor serves as a precise, factory-specification replacement component for a range of Buick and Chevrolet vehicles. It is designed to monitor the pressure within the engine's lubrication system, a vital function that helps protect the engine from damage due to low oil pressure. The sensor provides the engine control unit (ECU) with the necessary data to ensure optimal performance and can trigger warning lights if pressure falls outside safe parameters. It is an essential part for maintenance, repair, and diagnostic procedures where the original sensor has failed or is providing inaccurate readings. Compatibility is confirmed through the listed OEM part numbers, which include 12573107, 12567323, 12562230, 12614969, and 12616646.

Features and Construction

This sensor is built to meet the original equipment specifications for the applicable vehicle models. Its primary role is to provide a reliable electrical signal corresponding to the engine's oil pressure.

Material and Build

The sensor is constructed from automotive-grade materials engineered to withstand the high temperatures, vibrations, and potential fluid exposure found in an engine compartment. The housing is typically made from durable metals and plastics, while the internal sensing element is designed for accuracy and longevity under normal operating conditions. The electrical connector is keyed to match the vehicle's wiring harness, preventing incorrect connection.

Size and Practical Fit

The sensor's physical dimensions and thread specifications are manufactured to match the original part precisely, ensuring it screws directly into the engine block's designated port without modification. This direct-fit design eliminates guesswork during installation and guarantees the correct sealing and sensor positioning required for accurate pressure readings.

Uses and Placement

This sensor is a critical component for both routine vehicle maintenance and specific repair scenarios. Its correct function is integral to the vehicle's onboard diagnostic systems.

Event or Professional Use

For professional mechanics and workshops, this sensor is a standard service part used to address customer complaints related to oil pressure warning lights, erratic gauge readings, or diagnostic trouble codes (DTCs) pointing to the oil pressure circuit. It allows for a straightforward swap of a faulty component, restoring the vehicle's monitoring system to proper working order. Verifying the vehicle's VIN against the listed part numbers is a standard professional practice to ensure correct application.

Everyday Home Use

For the knowledgeable DIY enthusiast, replacing a failed oil pressure sensor can be a manageable task that resolves a persistent dashboard warning light. Using this direct-fit part simplifies the process, as it is designed to install in the same location as the original using common hand tools. Successfully replacing a faulty sensor can restore peace of mind regarding engine health without the need for a garage visit, provided the installer follows proper safety and procedural guidelines.

Benefits and Buying Value

Choosing this specific sensor offers practical advantages centred on fitment, function, and simplicity for the listed vehicle applications.

Reuse and Low Maintenance

Once installed, the sensor requires no regular maintenance. It is a fit-and-forget component under normal circumstances, performing its monitoring function continuously whenever the engine is running. Its value lies in restoring a fundamental engine protection system, potentially preventing more serious and costly engine damage that could result from undetected low oil pressure.

Why Choose This Product

This product is selected for its confirmed compatibility with the provided range of General Motors part numbers. It offers a solution tailored for owners of Buick Regal, Chevrolet Impala, Buick LaCrosse, and other models that use these specific sensor references. The primary benefit is the elimination of compatibility uncertainty, providing a component that is designed to interface correctly with your vehicle's engine management system, ensuring the oil pressure warning system operates as the manufacturer intended.
