Volvo
Our high-precision Turbo Speed Sensor is an essential component for modern Volvo heavy-duty engines. This sensor monitors the rotational speed of the turbocharger turbine, allowing the Engine Control Unit (ECU) to optimize boost levels and prevent “overspeed” conditions that can lead to catastrophic turbo failure.
Technical Specifications
-
Primary OE Reference: 21508269
-
Secondary OE Reference: 85151481
-
Sensor Type: Passive/Active Inductive (Speed/RPM)
-
Connector: 2-Pin / 3-Pin (Verify against specific engine harness)
Application Models
This sensor is compatible with a wide range of Volvo heavy-duty vehicles and engines, specifically optimized for the D11, D13, and D16 engine platforms:
-
Volvo FH Series: FH12, FH13, FH16
-
Volvo FM Series: FM9, FM11, FM13
-
Volvo VNL / VNM / VNR: (North American Models)
-
Volvo FMX: Construction and heavy-duty range
-
Volvo B-Series Buses: B11R, B13R
Key Product Advantages
-
OEM-Grade Accuracy: Calibrated to match Volvo’s strict engine management parameters for immediate ECU recognition.
-
High-Heat Resilience: Built with specialized shielding and high-temperature polymers to survive the extreme environment of the exhaust manifold.
-
Anti-Corrosion Housing: Treated surface to prevent sensor “seizing” in the turbocharger housing over time.
-
Fault Code Resolution: Directly replaces sensors causing MID 128 PID 103 or related turbocharger speed efficiency codes.
Manufacturer’s Note: A failing turbo speed sensor often results in reduced engine power, increased fuel consumption, or the engine entering “Limp Home” mode. Our 21508269 replacement provides a cost-effective, durable solution to restore your fleet’s uptime.
