BMW 1 3 Series E46 E87 E90 E91 Petrol N46 N46N Eccentric Shaft Sensor is a precision component of the petrol engine control system, responsible for the accurate reading of the eccentric shaft position in BMW N46 series units. This allows the engine control unit to properly manage valve operation and the variable valve timing system, which translates into stable engine performance and predictable throttle response. This solution is intended for users who want to restore correct engine operating parameters while maintaining compliance with BMW factory specifications.

Function and role of the eccentric shaft sensor

The eccentric shaft sensor in the N46 engine is responsible for monitoring the position of the component controlling valve operation, which is crucial for the proper functioning of the variable valve timing system. A properly functioning sensor allows the engine control unit to:

• precisely dose the air-fuel mixture in the petrol engine,
• stabilize idle speed and reduce misfires,
• ensure proper response to load and changes in rotational speed,
• reduce errors stored in the controller memory related to shaft position.

For BMW E87, E90, and E91 series power units with the N46 engine, using the appropriate sensor is important both from the point of view of mechanical durability and correct electronic diagnostics.

Compatibility and compliance with BMW

The offered element comes from the BMW group and is intended for use in N46 petrol engines used in 1 and 3 series E-generation models. Using an original solution from this brand allows for full compatibility with factory engine equipment, wiring harnesses, and controller software.

As a result, installation is predictable, and operating parameters after replacement are close to factory settings. This is particularly important for units experiencing symptoms such as rough cold running, power loss, or recurring errors related to the eccentric shaft position.

Product characteristics and practical application

The presented sensor is an item from the Other category, however, its function in the engine control system is strictly defined – it is responsible for providing an input signal to the controller, which then corrects the timing operation. In practice, replacing this component is often one of the basic service steps for:

• recurring errors related to the timing system in the N46 engine,
• problems with starting on a warm or cold engine,
• uneven engine operation at low speeds,
• diagnostics of faults related to the variable valve timing system.

Using an original BMW solution helps reduce the risk of incompatibility that may occur with replacements of uncertain origin.

Condition, verification, and selection by parameters

The item is offered as a used OEM component, which in practice means it has been removed from a vehicle and verified for further use. This type of solution is often chosen by users looking for a compromise between repair costs and maintaining the manufacturer's original specifications.

When selecting an eccentric shaft sensor for a specific BMW vehicle, it is worth using the manufacturer's markings and interchangeable numbers, as well as data such as SKU, OEM part number, or information about the brand and fuel type stored in the store system. This facilitates matching the element to a specific engine configuration and minimizes the risk of errors when ordering.
