GM Oil Pressure Sensor for Buick Regal and Chevrolet Models

This oil pressure sensor is a direct replacement component designed for specific Buick and Chevrolet vehicles. It functions as a critical part of the engine monitoring system, sending accurate oil pressure readings to the vehicle's computer and dashboard warning lights. Replacing a faulty sensor helps restore accurate pressure warnings and can be essential for maintaining proper engine health diagnostics. The listed compatibility ensures it matches the factory specifications for fitment and electrical operation in the intended applications.

Features and Construction

This sensor is manufactured to meet the requirements of the original vehicle systems. Its primary role is to provide a reliable electrical signal corresponding to the engine's oil pressure.

Part Number Compatibility

The sensor is confirmed as a direct replacement for several General Motors OEM part numbers. This includes 12573107, 12567323, 12562230, 12614969, and 12616646. An additional variant, listed as 12677836, is also confirmed as a compatible option. This range of part numbers covers the sensor requirements for a selection of Buick and Chevrolet models.

Fitment and Application

The source text specifies applicability to Buick and Chevrolet vehicle models. It is a precision electronic component intended for installation in the engine bay to monitor lubricant pressure. Correct installation is crucial for leak prevention and accurate signal transmission.

Uses and Placement

This sensor has a single, defined purpose within the vehicle's engine system. Its correct operation is integrated into the vehicle's broader electronic monitoring and driver alert systems.

Vehicle System Function

The oil pressure sensor threads into a port on the engine block, typically near the oil filter housing or main gallery. It converts the mechanical oil pressure into an electrical signal. This signal is used by the Engine Control Unit (ECU) for system management and to illuminate the oil pressure warning light on the instrument cluster if pressure falls below a safe threshold.

Replacement Scenario

This product is used when the original factory-fitted oil pressure sensor fails. Symptoms of a faulty sensor can include an illuminated oil pressure warning light despite correct oil level and pressure, an intermittent warning light, or an inaccurate oil pressure reading on vehicles equipped with a pressure gauge. Replacing the sensor addresses these electrical and signalling faults.

Benefits and Buying Value

The value of this component lies in its specified compatibility and its role in maintaining a critical vehicle warning system. It is a functional repair part rather than a cosmetic or upgrade item.

Accurate System Restoration

Using a sensor with confirmed part number compatibility helps ensure the vehicle's oil pressure monitoring system functions as the manufacturer intended. This restores a reliable early warning system for one of the most critical engine parameters, helping to prevent severe engine damage that can result from operating with low oil pressure.

Why Choose This Product

This sensor is listed for specific applications, providing a clear match for vehicles requiring the listed OEM part numbers. It offers a targeted solution for owners of compatible Buick and Chevrolet models needing to replace this specific engine sensor, ensuring the correct electrical characteristics and physical fit for the application.
