Genuine GM Oil Pressure Sensor Part Numbers 12573107 12567323 for Buick Regal and Chevrolet

This oil pressure sensor is a direct replacement component manufactured to GM's original specifications for use in vehicles including the Buick Regal and a selection of Chevrolet models. It is listed under several core part numbers—12573107, 12567323, 12562230, 12614969, 12616646, and 12677836—which define its exact physical and electrical characteristics. Replacing a faulty sensor with this unit restores the vital function of monitoring engine oil pressure, providing an accurate reading to your vehicle's dashboard gauge or warning light. This allows for the early detection of potential lubrication issues, which is a fundamental aspect of preventative engine maintenance. The part is supplied individually, ready for installation by a qualified mechanic or a knowledgeable DIY enthusiast with the appropriate tools and workshop manual for their specific vehicle.

Features and Construction

This sensor is defined by its GM part numbers, which guarantee its compatibility and fitment. The construction is based on the original equipment manufacturer (OEM) design for reliable integration into your vehicle's engine bay and electrical system.

Material and Build

The sensor is built using materials specified by GM for engine bay environments, including heat resistance and durability against exposure to engine oil. The electrical connector is designed to match the vehicle's original wiring loom, ensuring a secure connection that prevents moisture ingress or signal interruption. The internal sensing mechanism is calibrated to provide an accurate signal to the vehicle's engine control unit or dashboard instrument cluster.

Size and Practical Fit

The sensor's thread size, overall body dimensions, and connector orientation are precisely defined by the listed GM part numbers (12573107, 12567323, etc.). This ensures it will screw directly into the engine block's designated port and plug straight into the existing vehicle wiring harness without modification. This direct-fit design is crucial for a correct and reliable installation that maintains the vehicle's factory specifications.

Uses and Placement

This sensor has a single, defined purpose: to accurately measure the pressure of the engine oil within a compatible GM vehicle and communicate that data to the driver. Its placement is fixed within the engine's lubrication system.

Event or Professional Use

For professional mechanics and automotive workshops, this sensor is a standard service part used to address check engine lights or inaccurate oil pressure warnings on applicable Buick and Chevrolet vehicles. It is a critical replacement item when diagnosing oil pressure-related faults, ensuring the repaired vehicle meets OEM performance standards before being returned to the customer.

Everyday Home Use

For the competent home mechanic, replacing a failed oil pressure sensor can resolve a persistent dashboard warning light and restore peace of mind regarding basic engine health. It is a targeted repair for a specific symptom, undertaken when diagnostic steps have confirmed the sensor itself is faulty, not the engine's oil pump or lubrication system.

Benefits and Buying Value

The primary value of this part lies in its specification-matching design and its role in maintaining a fundamental vehicle warning system.

Reuse and Low Maintenance

The sensor itself is not a reusable or serviceable item; it is replaced as a complete unit when faulty. Its value comes from restoring a low-maintenance monitoring system. Once correctly installed, it should function reliably without any routine upkeep, allowing the vehicle's existing oil change schedule to be the primary maintenance focus for the lubrication system.

Why Choose This Product

You should choose this oil pressure sensor because it is specified by the authentic GM part numbers for your vehicle. This guarantees the correct thread, electrical output signal, and connector, preventing installation issues, dashboard errors, or potential damage from an ill-fitting pattern part. It provides a straightforward solution for a specific mechanical problem, backed by the engineering data of the part numbers listed.
