Crankshaft Position Sensor 12560228 213-354 for Buick & Chevrolet Engine Management

This crankshaft position sensor is an OE-specified component, identified by part numbers 12560228 and 213-354, intended as a direct replacement for Buick and Chevrolet vehicles. Its primary function within the engine bay is to monitor the rotational speed and position of the crankshaft, providing this critical data to the vehicle's powertrain control module (PCM). This input is fundamental for managing ignition timing, fuel injection pulses, and other engine functions that affect performance, emissions, and drivability. The sensor is supplied as a single, complete unit with external dimensions of 15x12x5 cm, ready for professional or knowledgeable DIY installation where compatible.

Features and Construction

The product is defined by its OE part numbers and specific vehicle compatibility. Its design and output signals are engineered to match the original equipment requirements for the listed applications.

Material and Build

While the source material does not detail the internal construction or housing materials, the sensor is presented as a fully assembled, functional electronic component. Its build is presumed to meet the necessary specifications for sensing magnetic or optical triggers from the crankshaft's reluctor wheel or tone ring and transmitting a corresponding signal to the engine computer.

Size and Practical Fit

The sensor's physical footprint is clearly stated as 15 cm in length, 12 cm in width, and 5 cm in height. These dimensions are relevant for installers checking clearance within the engine compartment, particularly around the crankshaft pulley or transmission bellhousing area where these sensors are typically mounted. Its compact size is a practical consideration for fitting into the engineered space on compatible Buick and Chevrolet models.

Uses and Placement

This sensor serves a single, defined purpose within the vehicle's engine management system. Its use is tied directly to maintaining or restoring factory-specified engine operation.

Event or Professional Use

For professional mechanics or advanced enthusiasts, this sensor is a service part used to address specific fault codes related to crankshaft position, such as those indicating a faulty sensor signal, erratic engine timing, or a no-start condition. Its correct installation is critical for restoring the PCM's ability to synchronise fuel injection and ignition events accurately.

Everyday Home Use

For the DIY vehicle owner tackling a confirmed sensor failure, this unit provides the exact replacement component needed. Its application is highly specific: it replaces a failed sensor on a Buick or Chevrolet to resolve drivability issues like hard starting, stalling, poor acceleration, or an illuminated check engine light where diagnosis points to the crankshaft position sensor circuit.

Benefits and Buying Value

The value of this product lies in its direct applicability and role in vehicle functionality, rather than aesthetic or comfort features.

Reuse and Low Maintenance

As an electronic sensor, it is not a reusable or maintainable item in the traditional sense. Its value is in being a one-time replacement that, once installed correctly, should function for the service life of the component without requiring any routine maintenance, cleaning, or adjustment from the user.

Why Choose This Product

This sensor is chosen specifically because it matches the original equipment numbers (12560228, 213-354) for Buick and Chevrolet vehicles. This match is the primary reason for selection, as it ensures electrical compatibility and physical fitment, aiming to restore the vehicle's engine management system to its designed operational parameters without requiring modifications or signal adapters.
