Buick Chevrolet Crankshaft Position Sensor: Direct Replacement Part 12560228 213-354

This crankshaft position sensor is designed as a direct replacement component for specific Buick and Chevrolet models, identified by the original equipment (OE) part numbers 12560228 and 213-354. It serves a critical function in the engine management system by monitoring the position and rotational speed of the crankshaft. This data is sent to the powertrain control module (PCM) to calculate precise ignition timing and fuel injection pulses. A faulty sensor can lead to poor engine performance, starting difficulties, or illumination of the check engine light. This unit provides a solution for those specific repair scenarios, with its compact form factor designed to fit the original mounting location.

Features and Construction

The sensor's primary feature is its defined compatibility, making it a targeted solution for certain GM vehicles. Its construction is focused on performing reliably in the high-temperature and vibrational environment of an engine bay.

Material and Build

The sensor is built from materials typical for automotive electronic components, including a durable plastic or metal housing to protect the internal magnetic or Hall-effect sensing element. These materials are selected to withstand engine compartment temperatures and exposure to fluids like oil and coolant, though specific material grades are not detailed in the source. The electrical connector is designed to mate securely with the vehicle's wiring harness.

Size and Practical Fit

The provided dimensions of 15cm in length, 12cm in width, and 5cm in depth are crucial for installation. This size indicates the physical space the sensor occupies, ensuring it will fit within the constraints of the engine bay on compatible models. It is a self-contained unit supplied individually, so mechanics or DIY installers must source any required mounting bolts or seals separately if they are not reusable from the old sensor.

Uses and Placement

This sensor has a single, well-defined use: to restore proper crankshaft position signal input to a vehicle's engine control system. Its placement is always in proximity to the engine crankshaft, often near the harmonic balancer, transmission bellhousing, or engine block.

Event or Professional Use

For professional automotive technicians, this part is a line-item replacement for a diagnosed fault. It is used when diagnostic trouble codes related to crankshaft position sensor circuits (e.g., P0335) are present, or when symptoms like a no-start condition or erratic idle point to a failed sensor. Its OE-referenced part numbers allow for quick, confident identification in a workshop environment.

Everyday Home Use

For the experienced home mechanic, this sensor represents a manageable repair task for a vehicle they own, assuming they have the correct tools and access to service information. It addresses a clear problem—a faulty sensor—with a direct solution. Success depends on correctly identifying the failed component and safely performing the replacement without damaging the new sensor or surrounding components.

Benefits and Buying Value

The value of this product lies in its specificity and function. It solves a discrete problem for a defined set of vehicles, returning the engine management system to proper operation.

Reuse and Low Maintenance

As an electronic component, the sensor itself is not a maintenance item but a replace-on-failure part. Its value is in restoring the original function of a system that requires no regular upkeep. Proper installation is the key to its longevity, as damage from improper handling or contamination during fitting is the primary avoidable cause of premature failure.

Why Choose This Product

You would select this specific sensor if your Buick or Chevrolet vehicle requires a part numbered 12560228 or 213-354. The decision is based on an exact match to the original specification, not on comparative features with other brands. Its defined compatibility is its primary advantage, aiming to provide a correct fit and expected performance for the targeted application.
