Crankshaft Position Sensor Replacement for Buick and Chevrolet Vehicles with OE Number 12560228

This crankshaft position sensor is a crucial engine management component designed as a direct replacement for original equipment parts bearing the identification numbers 12560228 and 213-354. It is specified for use in various Buick and Chevrolet models, where it serves the essential function of monitoring the crankshaft's rotational speed and position. This real-time data is sent to the vehicle's powertrain control module (PCM), which uses it to calculate precise timing for fuel injection and ignition spark. A faulty sensor can lead to a range of driveability issues, including engine misfires, stalling, hard starting, and illuminated warning lights. This replacement unit aims to restore that critical signal path with a part engineered to match the original fit and electrical characteristics. With compact external dimensions of 15 cm by 12 cm by 5 cm, it is built to occupy the same space as the factory component.

Features and Construction

This sensor is defined by its specific application data and physical form, providing a targeted solution for engine repair. The primary information available concerns its compatibility and size, which are key factors for a successful installation.

Material and Build

The source text does not detail the specific plastics, metals, or internal electronics used in the sensor's construction. Automotive crankshaft sensors are typically housed in a durable, heat-resistant material to withstand engine bay temperatures and contain a magnetic pickup or Hall-effect sensor. This unit is designed to interface directly with the vehicle's existing wiring connector and mount using the original hardware points, as indicated by its listed OE and cross-reference numbers. Its purpose is to replicate the signal output and physical footprint of the original part it replaces.

Size and Practical Fit

The sensor's dimensions are precisely given as 15 cm in length, 12 cm in width, and 5 cm in height. This compact form factor is essential for fitting into the often-crowded space near the engine's crankshaft, typically at the front or rear of the engine block, bellhousing, or within the crankcase. The stated size allows installers to verify the part will physically clear surrounding components like hoses, brackets, and the engine block itself before beginning work. The product is supplied as one single unit, which is the standard for this type of component.

Uses and Placement

This sensor has a single, well-defined purpose within the vehicle's engine management system. Its use is not optional but mandatory for the engine to run correctly, and its placement is dictated by the vehicle manufacturer's design.

Event or Professional Use

For professional mechanics or experienced DIY enthusiasts, this sensor is a repair part used to resolve specific fault codes related to crankshaft position circuit issues (such as P0335). It is installed during engine diagnostics and repair procedures when testing indicates a failed or out-of-specification sensor. The work involves locating the old sensor, disconnecting its electrical plug, unbolting it, and installing the new unit, often requiring basic hand tools. The provided OE numbers are critical for professionals to ensure the correct part is sourced for the specific vehicle on the lift.

Everyday Home Use

For the home mechanic tackling their own vehicle maintenance, this sensor represents a solution to restore their daily driver's performance and reliability. Symptoms prompting replacement include the car failing to start, stalling at idle or low speeds, experiencing a noticeable loss of power, or the illumination of the 'Check Engine' light. Successfully replacing a faulty crankshaft sensor can eliminate these problems, returning the vehicle to normal operation without the need for a costly garage visit, provided the installer has the correct tools and follows proper safety and procedural guidelines.

Benefits and Buying Value

The value of this part lies in its defined compatibility and role in restoring essential engine function, rather than in unspecified premium materials or extended warranties.

Reuse and Low Maintenance

Crankshaft position sensors are not maintenance items with a scheduled replacement interval; they are typically replaced only upon failure. Therefore, the value proposition is one of repair, not periodic upkeep. Once installed, a functioning sensor should continue to operate for many years under normal conditions. The product offers no specific data on lifespan or reliability metrics, so its long-term value is based on its correct installation and the inherent duty cycle of such components.

Why Choose This Product

This sensor is chosen because it matches the OE numbers 12560228 and 213-354 for Buick and Chevrolet applications. This direct correlation is the most important factor, reducing the risk of ordering an incompatible part. The provided dimensional data (15x12x5 cm) offers a secondary check for fitters familiar with the engine bay. The alternative would be a generic sensor claiming broad compatibility, which may require wiring adapters or bracket modifications. This unit is presented as a plug-and-play solution for the specified vehicles, aiming for a straightforward installation process that returns the engine management system to its designed state.
