ELyo0000819 — Tachometer Speed Sensor Voe20450707 For Volvo Excavator Ec240Blc Ec290Blc Ec210B Ec160B Ec240B Ec290B

This tachometer speed sensor accurately measures the rotational speed of the engine or transmission, providing crucial data for the instrument cluster and engine control unit. Manufactured to meet exact OEM specifications, it offers reliable and precise readings unlike worn sensors that can cause intermittent or incorrect speed displays. Operators might notice the tachometer needle fluctuating erratically, dropping to zero while the engine is running, or failing to register any RPMs.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A faulty tachometer speed sensor may cause the RPM gauge to become erratic, showing inconsistent readings or dropping to zero unexpectedly. If the issue progresses, the tachometer may cease functioning entirely, providing no indication of engine speed. This lack of information can hinder proper engine operation and diagnostics.

Installation Tip

Ensure the mounting surface on the engine or flywheel housing is clean and free of metal shavings before installing the sensor. Avoid using excessive force when tightening, as this can damage the sensor threads or housing.

Service Note

Inspect the wiring harness and connectors leading to the sensor for any signs of damage or corrosion, and check the engine's flywheel or crankshaft for any obstructions when replacing the tachometer speed sensor.
