Bosch Crankshaft Reference Mark Sensor

The Bosch Crankshaft Reference Mark Sensor (also called a crankshaft position sensor or crank sensor) monitors the position and rotational speed of the crankshaft. It sends this signal to the engine control unit (ECU). The ECU uses the signal to time fuel injection and ignition accurately, which supports smooth running and efficient combustion.

Key Features:

• Gives the engine control unit a reliable crankshaft reference signal for ignition and injection timing
• Made to Bosch's OE-level standards for accuracy and consistency
• Built for the heat, vibration, and oil exposure found in the engine bay
• Helps prevent hard starting, stalling, misfires, rough idle, and a lit check engine light caused by a failing sensor
• Designed for straightforward replacement
