Vemo V33-72-0003 Sensor, crankshaft pulse

Vemo V33-72-0003 Crankshaft Pulse Sensor

The Vemo V33-72-0003 is a high‑performance crankshaft pulse generator designed for modern internal combustion engines. It delivers precise timing signals to the engine control unit (ECU), enabling accurate fuel injection, ignition timing, and overall engine management.

Key Functionalities

• Pulse Generation: Converts crankshaft rotation into a series of electrical pulses that represent engine position.
• High Accuracy: Maintains timing precision within ±0.5° of crankshaft angle, ensuring optimal combustion.
• Robust Construction: Built with high‑temperature resistant materials to withstand the harsh environment inside an engine bay.
• Compact Design: Small footprint allows easy installation in tight spaces typical of modern vehicle engines.

Technical Specifications

Installation Guidelines

1. Preparation: Ensure the crankshaft is clean and free of oil or debris before mounting.
2. Alignment: Position the sensor so that its magnetic core aligns precisely with the crankshaft gear teeth.
3. Screw Securely: Tighten mounting bolts to the manufacturer’s torque specification (typically 15 Nm).
4. Wire Connections: Connect the sensor leads to the ECU or engine management module using shielded cables to reduce electromagnetic interference.
5. Testing: Verify pulse output with an oscilloscope or diagnostic tool while the engine is cranking.
