VEMO Pulse Sensor, flywheel V24-72-0011

VEMO Pulse Sensor – Flywheel V24-72-0011

The VEMO Pulse Sensor, model V24-72-0011, is a high‑performance crankshaft pulse generator designed for modern internal combustion engines. It delivers precise engine timing information to the Engine Control Unit (ECU), enabling accurate fuel injection, ignition control, and overall engine management.

Core Functionality

This sensor operates by generating electrical pulses each time a specific reference point on the crankshaft passes its magnetic field. The ECU interprets these pulses to determine:

• Crankshaft position – critical for synchronizing fuel and ignition events.
• Engine speed (RPM) – used for throttle control, idle regulation, and safety limits.
• Timing of the engine cycle – essential for variable valve timing systems and cylinder deactivation.

Design & Construction

The V24-72-0011 features a robust housing that protects the internal magnetic assembly from oil, heat, and vibration. Key design elements include:

• High‑temperature insulation capable of operating up to 200 °C.
• Low‑friction bearing interface ensuring long life even under high RPM conditions.
• Compact dimensions (approx. 30 mm × 20 mm) for easy integration into tight engine bays.
• Standardized mounting flange compatible with most OEM crankshaft designs.

Electrical Characteristics

The sensor outputs a square wave signal with the following specifications:

• Signal type: Bipolar pulse (positive and negative).
• Voltage range: 0.5 V to 2.5 V peak‑to‑peak.
• Current consumption: < 10 mA at operating temperature.
• Signal frequency: Up to 12,000 Hz (corresponding to ~90,000 RPM).

Compatibility & Applications

The V24-72-0011 is engineered for a wide range of vehicles and engines. Common applications include:

• Passenger cars – Fiat, Peugeot, Citroën, Renault, Lancia, Ferrari.
• Light commercial vehicles – Trucks and vans requiring robust engine monitoring.
• Performance engines – High‑revving motors where precise timing is critical.

Its universal mounting design allows it to replace OEM crankshaft sensors in most models without the need for extensive modifications.

Installation Guidelines

1. Preparation: Disconnect the battery and remove any protective covers around the crankshaft area.
2. Removal of old sensor: Unscrew the existing pulse generator using a suitable socket. Carefully detach the wiring harness, noting polarity.
3. Mounting new sensor: Align the V24-72-0011 with the crankshaft reference point and secure it with the supplied bolts. Ensure the magnetic face is flush against the rotating element.
4. Wiring: Connect the harness, preserving correct polarity (positive to positive, negative to ground). Use heat‑shrink tubing or electrical tape for insulation.
5. Testing: Reconnect the battery and start the engine. Verify that the ECU registers a stable RPM signal and that no error codes appear.

Maintenance & Troubleshooting

Although designed for durability, routine checks can preempt failures:

• Visual inspection: Look for cracks or corrosion on the housing and wiring.
• Signal verification: Use an oscilloscope to confirm pulse shape and frequency. A flat line indicates a fault.
• Connector integrity: Tighten all terminal screws and replace any damaged connectors.
• Environmental protection: Ensure the sensor remains free from oil leaks or excessive heat sources.
