Car sensor, automotive sensor, for universal sensors, compatible with General Motors vehicles, OE references 12561218 12561211 PC273 5S125321336, suitable for general automotive use, in black colour, for engine management and diagnostic systems
Universal Automotive Sensor for General Motors Vehicles: Black Replacement Part

This automotive sensor serves as a universal replacement component designed for compatibility with a range of General Motors (GM) vehicles. It is specified for general application within vehicle engine management and diagnostic systems, acting as a direct substitute for several common Original Equipment (OE) manufacturer references. Supplied as a single unit in a black finish, it simplifies the parts lookup process for mechanics and DIY enthusiasts by consolidating multiple part numbers into one item. Its primary function is to integrate with the vehicle's electronic control unit (ECU) to monitor and relay data for optimal engine performance.
Features and Construction

This sensor is built to meet the electrical and environmental specifications required for modern vehicle sensor systems. Its design allows it to interface correctly with the vehicle's wiring loom and ECU.
Material and Build
The sensor is constructed from standard automotive-grade materials, including plastics and metals, designed to withstand typical under-bonnet temperatures and vibrations. The black housing provides a neutral finish that is consistent with many OEM components. The internal electrical components are engineered to provide accurate signal transmission for the vehicle's onboard computer systems.
Compatibility and Fit
Its key feature is broad compatibility, replacing the OE numbers 12561218, 125612110, PC273, and 5S125321336. It also corresponds to the aftermarket model numbers 147458, SU1277, 714551, CSS1531, SN2001, S10127, and S10080. This wide cross-reference capability makes it a versatile choice for workshops stocking parts for GM vehicles, reducing the need to hold multiple individual SKUs for what is often the same functional component.
Uses and Placement

This sensor is intended for use in the engine bay or other relevant locations as specified by the vehicle manufacturer's original sensor placement.
Professional Workshop Use
For professional mechanics, this sensor offers a reliable, single-sku solution for common GM sensor replacements, aiding in efficient inventory management and faster job turnaround. The clear OE cross-reference list helps ensure correct part selection first time, reducing errors and customer vehicle downtime.
Home Mechanic and DIY Use
For the knowledgeable home mechanic, this sensor provides a accessible replacement option for general sensor faults on compatible GM models. Users should always verify fitment using their vehicle's VIN or existing old part number against the provided compatibility list before purchase and installation to ensure correct application.
Benefits and Buying Value

The value of this product lies in its consolidation of multiple part numbers and its role in maintaining vehicle performance.
Simplified Parts Sourcing
The primary benefit is the simplification of the parts sourcing process. Instead of searching for one specific OE number that may be discontinued or expensive, this universal sensor covers several references, increasing the likelihood of finding a suitable part. This can be particularly useful for maintaining older GM vehicles where original parts are less readily available.
Why Choose This Product
Choose this sensor for a straightforward, general-purpose replacement when your GM vehicle's diagnostic system indicates a sensor fault and the old part corresponds to one of the listed numbers. It provides a functional solution aimed at restoring the vehicle's monitoring capabilities without the complexity of sourcing an exact, model-year-specific OEM part, provided compatibility is confirmed.
