Crankshaft Position Sensor 12560228 213-354 for Buick and Chevrolet Vehicles

This crankshaft position sensor is a critical electronic component for the engine management systems of applicable Buick and Chevrolet models. Identified by the manufacturer codes 12560228 and 213-354, it serves as a direct replacement for the original factory part. The sensor's primary function is to monitor the exact rotational position and speed of the engine's crankshaft, transmitting this vital data to the vehicle's powertrain control module (PCM). This information is fundamental for the precise calculation of ignition timing and fuel injection pulses, directly influencing engine performance, efficiency, and emissions control. A correctly functioning sensor is therefore essential for reliable engine operation.

Features and Construction

This sensor is built to the specifications required for seamless integration into the engine bay of targeted vehicle models. Its design prioritises accurate signal generation and durability in the challenging under-bonnet environment.

Material and Build

The sensor features a robust housing typically constructed from heat-resistant engineering plastics or composites, protecting the internal magnetic or Hall-effect sensing element from exposure to oil, dust, and high temperatures. The electrical connector is designed to mate securely with the vehicle's wiring harness, ensuring a reliable signal path resistant to vibration and moisture ingress, which are common causes of sensor failure.

Size and Practical Fit

With compact external dimensions of 15 centimetres in length, 12 centimetres in width, and 5 centimetres in depth, the sensor is engineered to fit into the often confined space adjacent to the engine crankshaft, usually near the bottom of the engine block or the transmission bell housing. Its specific shape and mounting provisions correspond directly to the original part, allowing for a straightforward installation process that does not require modification to the vehicle.

Uses and Placement

This component has a singular, focused application but is indispensable for the modern internal combustion engine's electronic control systems.

Event or Professional Use

For professional automotive technicians and repair workshops, this sensor is a standard inventory item for servicing and repairing the engine management systems of the specified Buick and Chevrolet vehicles. It is used to address fault codes related to crankshaft position, such as those indicating a loss of signal or implausible data, which can cause symptoms like hard starting, stalling, poor acceleration, or illumination of the check engine light.

Everyday Home Use

For the vehicle owner or DIY enthusiast, this sensor represents a key part for resolving drivability issues traced to a faulty crankshaft position sensor. Replacing a failing sensor with this direct-fit unit can restore smooth engine operation, reliable starting, and optimal fuel economy. It is supplied as a single, complete unit, ready for installation to rectify a specific problem.

Benefits and Buying Value

Choosing this specific part number offers practical advantages focused on compatibility and functional restoration.

Reuse and Low Maintenance

The sensor itself is a sealed unit with no user-serviceable parts and is designed as a replace-on-failure component. Its value lies in its precise specification matching, which allows for the reliable restoration of the vehicle's original engine management function without the need for ongoing maintenance of the part itself once installed.

Why Choose This Product

This sensor is selected for its verified compatibility with the listed vehicle makes and models, as indicated by the OE part numbers 12560228 and 213-354. It provides a solution for a very specific technical need—restoring the critical crankshaft position signal. The value is in its function: enabling the engine's computer to once again manage ignition and fuel delivery correctly, which is fundamental to the vehicle's operation.
