VOLVO 20508011 Crankshaft Speed & Position Sensor Specification

Genuine VOLVO Crankshaft Speed & Position Sensor 20508011

Product Overview: The Genuine VOLVO Crankshaft Speed & Position Sensor (P/N: 20508011 / VOE20508011) is a high-precision electromagnetic sensor mounted on the flywheel housing. It monitors engine rotation speed and angular position by reading the flywheel gear teeth, sending real-time data to the ECU to synchronize fuel injection, cylinder balance, and idle control.

1. Core Technical Advantages

  • Magnetic Pick-up: Premium internal windings ensure high-fidelity signal output even during low-RPM cranking.

  • Thermal & Chemical Durability: Built to withstand hot oil, clutch dust, and extreme heat within the flywheel housing.

  • EMI Shielding: Braided harness prevents electromagnetic interference from high-current electrical systems.

  • Fluid-Tight Seal: Includes Viton O-ring sealing to prevent oil leakage at the sensor port.

3. Master Application Fleet Guide

This sensor is essential for the timing integrity of numerous VOLVO platforms:

  • Crawler Excavators: EC210/B, EC240/B, EC290/B, EC330B/C, EC360B/C, EC460B/C

  • Other Systems: Volvo FH/FM/NH trucks (D12 engines), A-series haulers, and Penta industrial units.

4. Common Field Failure Symptoms

  • Crank-No-Start: Shorted windings result in zero signal, preventing the ECU from initiating fuel injection.

  • Sudden Stalling: Signal loss due to heat expansion can cause immediate engine shutdown, often failing to restart until cooled.

  • Rough Idling: Metal debris accumulation on the sensor tip causes signal distortion, leading to misfires and surging.

Best Practice Installation Advisory:
Proper air-gap clearance is critical. Clean the mounting surface thoroughly and always install a fresh, lubricated 190252 O-ring. Avoid magnetic debris during installation. Once secured, apply dielectric grease to the connector and clear stored fault codes via Volvo Tech Tool. Always verify S/N for harness compatibility before ordering.
