VEMO RPM Sensor – Engine Management V22-72-0019

The VEMO RPM Sensor (Model V22‑72‑0019) is a precision-engineered component designed to provide accurate engine speed measurement for modern automotive powertrains. It plays a pivotal role in the vehicle’s electronic control unit (ECU) by delivering real-time revolutions per minute (RPM) data, enabling optimal fuel injection timing, ignition control, and overall engine performance.

Key Functionalities

• High-Resolution RPM Measurement: The sensor captures crankshaft position with exceptional accuracy, ensuring the ECU receives precise speed information across a wide range of operating conditions.
• Robust Signal Output: It emits a clean, low-noise digital pulse train that is easily interpreted by the engine control module. This reliability reduces the likelihood of misfires or timing errors.
• Wide Operating Temperature Range: Designed to withstand extreme automotive environments, the sensor maintains performance from -40 °C to +120 °C, making it suitable for both high-performance and everyday vehicles.
• Compact and Durable Construction: The compact housing protects internal components from oil, coolant, and mechanical shock while keeping the overall weight minimal.

Applications Across Vehicle Platforms

The V22‑72‑0019 is engineered to fit a broad spectrum of manufacturers and models. Its versatility makes it an ideal choice for:

• Peugeot, Citroën, and Lancia vehicles – including the Xsara Picasso, Berlingo, C5, and various Peugeot 406 variants.
• Fiat and Suzuki models that require a reliable crankshaft pulse sensor for engine management systems.
• High-performance and racing applications where precise RPM data is critical for tuning and performance optimization.

Installation and Compatibility

The sensor’s design aligns with standard OEM mounting points, allowing straightforward replacement of original units. Key installation steps include:

1. Disconnect the battery to ensure safety during removal.
2. Remove the old sensor by unscrewing the mounting bolts and gently detaching the wiring harness.
3. Align the new V22‑72‑0019 with the crankshaft pulley or gear, ensuring proper positioning relative to the engine’s timing marks.
4. Screw in place using the supplied mounting hardware and reconnect the wiring harness.
5. Reconnect the battery and perform a diagnostic check to confirm sensor operation.

Performance Benefits

Integrating the V22‑72‑0019 into an engine management system yields several tangible advantages:
