Bosch 911 606 215 03 Crankshaft Reference Mark Sensor - 911 606 215 03

The Bosch 911 606 215 03 is an OEM-quality crankshaft reference mark sensor designed as a precise replacement for Porsche applications. Also referred to as a crankshaft position sensor or reference mark position sensor, this component is a critical part of the engine management system.

The reference mark sensor monitors the rotational position and speed of the crankshaft, delivering real-time data to the engine control module (ECM). This data allows the ECM to precisely time fuel injection and ignition events for optimal combustion efficiency. The sensor also plays a role in detecting engine misfires by identifying irregularities in crankshaft rotation.

Key Features:

• OEM-quality Bosch construction for direct-fit replacement
• Monitors crankshaft rotational position and speed
• Provides critical input to the engine control module for fuel injection and ignition timing
• Robust design engineered to withstand temperature fluctuations, mechanical vibrations, and exposure to engine fluids
• Enlarged operating temperature range for improved reliability under extreme engine conditions
• Reduced signal drift over the sensor's lifetime for long-term accuracy

The Bosch 911 606 215 03 is a direct OEM-equivalent sensor delivering the precision and durability expected from Bosch, one of the world's leading suppliers of original equipment automotive components.
