Impulse Sender, Crankshaft. Porsche 95B.2 Macan 2.0L Petrol MKII 2019-21  ❭  95890643302

The BOSCH Impulse Sender, Crankshaft is a engine management sensor, designed to monitor the exact position and rotational speed of the crankshaft. Often referred to as a crankshaft position sensor, this impulse sender provides critical timing information to the engine control unit (ECU), allowing precise control of fuel injection, ignition timing, and overall engine operation.

Fits:

• Porsche 95B.2 Macan Petrol 2.0L (245Bhp) 2019-21

Mounted near the crankshaft or flywheel, the sensor detects rotational impulses generated by a trigger wheel and continuously transmits this data to the ECU. It delivers reliable signal accuracy, durability, and seamless integration with Porsche engine management systems.
