Buick Chevrolet Crankshaft Position Sensor 12560228 213-354 for Engine Powertrain Control

This crankshaft position sensor, identified by OE part number 12560228 213-354, serves as a direct replacement component for specific Buick and Chevrolet vehicles. Its primary role within the engine management system is to monitor the rotational position and speed of the crankshaft, providing critical data to the powertrain control module. This information is fundamental for calculating precise ignition timing and fuel injection parameters, directly influencing engine performance, efficiency, and emissions. Sourcing the correct OE-numbered part ensures compatibility and reliable operation, making it a key component for both routine maintenance and repair scenarios where sensor failure is suspected.

Features and Construction

The sensor is designed as a plug-and-play replacement, matching the original equipment specifications for a straightforward installation process. Its construction is tailored to withstand the engine bay environment, transmitting accurate positional data to the vehicle's electronic control unit.

Material and Build

As a standard engine sensor, it is built from materials suitable for high-temperature and high-vibration automotive applications. The external housing protects the internal magnetic or Hall-effect sensing elements and electronics responsible for generating the signal based on crankshaft rotation. The specific plastic compound or metal used for the housing is not detailed, but its design is focused on durability and reliable signal transmission.

Size and Practical Fit

The sensor's physical footprint is compact, measuring 15 cm in length, 12 cm in width, and 5 cm in height. These dimensions are crucial for verifying it will fit within the allocated space on the engine block or transmission bell housing of compatible vehicles. The size ensures it can be mounted correctly using the original fastener points and that the sensing tip is positioned at the proper distance from the crankshaft's reluctor wheel or tone ring.

Uses and Placement

This component is essential for the vehicle's onboard diagnostics and smooth engine operation. It is used whenever the original sensor requires replacement due to wear, damage, or fault codes related to crankshaft position.

Event or Professional Use

For professional mechanics and repair workshops, this sensor is a standard inventory item for servicing Buick and Chevrolet models that use this specific OE reference. Its use is indicated when diagnostic tools flag codes such as P0335 (Crankshaft Position Sensor "A" Circuit) or related drivability issues like hard starting, stalling, or poor acceleration linked to faulty timing data. The correct OE number eliminates guesswork during parts lookup and ordering.

Everyday Home Use

For the knowledgeable DIY enthusiast, replacing a faulty crankshaft sensor can be a manageable project to restore vehicle performance and avoid costly garage labour. This part provides a clear, match-by-number solution. Successful installation typically requires basic mechanical tools, the ability to locate the sensor on the engine, and care when handling the electrical connector to avoid damage to the pins.

Benefits and Buying Value

Choosing this specific sensor part number offers clear practical advantages centred on fit, function, and sourcing confidence.

Reuse and Low Maintenance

Once installed, the sensor performs its function without routine maintenance. It is a fit-and-forget component under normal operating conditions until it reaches the end of its service life. Its value lies in restoring the engine management system to full functionality, which can prevent further issues like misfires or poor fuel economy that may arise from incorrect timing data.

Why Choose This Product

The primary reason to choose this product is the exact OE part number match (12560228 213-354), which guarantees application correctness for the intended Buick and Chevrolet vehicles. This eliminates compatibility risks associated with generic or cross-reference parts that may have subtle differences in connector shape, mounting bracket, or electrical output characteristics. The provided dimensions (15x12x5cm) also offer a tangible check for physical fit before purchase.
