Vemo V24-72-0018 Sensor, crankshaft pulse

Vemo V24-72-0018 Sensor – Crankshaft Pulse Generator

The Vemo V24-72-0018 is a high‑precision crankshaft pulse generator, also known as a crankshaft position sensor. It delivers accurate rotational data to the engine control unit (ECU), enabling optimal fuel injection, ignition timing, and overall engine performance.

Key Functionalities

• Pulse Generation: Produces a series of electrical pulses that correspond to the crankshaft’s rotation. Each pulse marks a specific angular position.
• High Accuracy: Maintains positional tolerance within ±0.5°, ensuring reliable engine timing even under high‑RPM conditions.
• Robust Signal Output: Generates a clean, low‑noise signal suitable for modern ECUs that require precise input for variable valve timing and cylinder deactivation.

Technical Specifications

Compatibility and Applications

The V24-72-0018 is engineered for a wide range of automotive platforms. It is commonly found in:

• Fiat models such as the Coupé, Marea, Marengo, Brava, Bravo, and Lancia Ypsilon.
• Other European vehicles that employ a similar crankshaft design.
• Custom engine builds where precise crank position feedback is essential.

Installation Guidelines

1. Preparation: Disconnect the battery and remove any existing sensor or generator. Clean the mounting surface to eliminate debris.
2. Mounting: Align the sensor’s magnetic core with the crankshaft gear teeth. Secure it using the supplied bolts, ensuring a torque of 15 Nm (or as specified by the vehicle manufacturer).
3. Electrical Connection: Connect the sensor leads to the ECU or dedicated signal harness. Verify polarity: positive supply (+12/24 V) and ground.
4. Testing: After installation, start the engine and observe the pulse output using a diagnostic scanner or oscilloscope. Confirm that the frequency matches expected RPM values.
5. Tuning (if necessary): Adjust sensor position slightly to fine‑tune phase alignment for optimal ignition timing.

Diagnostic Features

The V24-72-0018 incorporates built‑in diagnostics:

• No‑Signal Detection: The ECU can flag a missing pulse, indicating sensor failure or wiring issues.
• Pulse Rate Monitoring: Continuous monitoring of pulse frequency helps detect mechanical wear or misalignment.
• Temperature Compensation: Internal circuitry adjusts output to maintain accuracy across temperature variations.

Maintenance and Longevity

• Regularly inspect wiring harnesses for corrosion or damage, especially in high‑humidity environments.
• Avoid exposing the sensor to excessive oil mist or coolant leaks; these can degrade magnetic performance over time.
• Replace the sensor if diagnostic codes indicate a fault that cannot be resolved by cleaning or re‑soldering connections.
