Dorman 917-600 Engine Variable Valve Timing (VVT) Eccentric Shaft Position Sensor

BMW VVT Eccentric Shaft Sensor Replacement

Dorman 917-600 is an engine variable valve timing eccentric shaft position sensor built for BMW applications that use this style of sensor. It addresses a common OE failure point caused by oil seepage at the spot welds, using a stronger ultrasonic weld to help keep contamination out of the sensor body.

• Round connector shape with pin-style terminal configuration
• Black color/finish for a clean OE-style appearance
• Includes mounting hardware for the listed application
• OE FIX design focused on improving the original sensor weak point
• Direct replacement for BMW VVT eccentric shaft sensor service

How This Sensor Works

This eccentric shaft position sensor monitors the variable valve timing system on select BMW engines and sends position data to the engine control system. When the original sensor is affected by oil intrusion, signal quality can drop and drivability issues can follow. Dorman 917-600 is engineered as a replacement for BMW 550i, 650i, X5, 750i, 750Li, 760Li, 545i, 760i, 645Ci, 745i, and 745Li applications across the listed model years.

This part cross-references BMW 11377513784 and ECS1001 for the same application.

Common Problems It Can Address

• Check engine light related to eccentric shaft sensor performance
• Rough idle or inconsistent engine operation tied to VVT signal loss
• Oil contamination inside the original sensor housing
• Intermittent sensor readings from a failing OE weld seam
• Drivability concerns on BMW VVT-equipped engines

Installation Notes

Verify connector shape, terminal configuration, and engine application before installation. Inspect the mounting area for oil residue or connector damage, and replace any contaminated seals or related components as needed. Use the included mounting hardware during service and confirm proper sensor seating after installation.

Quality Assurance

Dorman designs this OE FIX replacement to correct a known failure mode in the original sensor by using a stronger ultrasonic weld. That construction change is intended to improve resistance to oil contamination in the same BMW engine applications.
