85151481 — Turbocharge Speed Sensor 85151481 21508269 For Volvo Truck Fh4 Vhd Vnm Vnl Vah

This turbocharger speed sensor is a critical sensor within the engine's turbocharging system, accurately measuring the rotational speed of the turbocharger's turbine or compressor shaft. It is manufactured to precise specifications, ensuring accurate data transmission to the engine control unit (ECU) for optimal turbo performance and fuel efficiency, unlike a faulty sensor that provides erratic or incorrect readings. Observable symptoms of a failing sensor include a loss of engine power, increased exhaust smoke, and the illumination of the check engine light.

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

The first indication of a failing turbocharger speed sensor is often a noticeable reduction in engine power and responsiveness. If ignored, the turbocharger may not engage correctly, leading to increased fuel consumption and potentially damaging exhaust emissions. The ultimate consequence is compromised engine performance and potential damage to the turbocharger or engine.

Installation Tip

Clean the sensor mounting port thoroughly before installation to ensure a proper seal and accurate readings. Avoid using excessive force when threading the sensor into the turbocharger housing, as this can damage the internal threads.

Service Note

Inspect the turbocharger itself for any signs of oil leaks or excessive play in the shaft when replacing the speed sensor.
