Volvo AT Speed Sensor - Genuine Volvo 30787675

Product Information

The vehicle speed sensor (VSS) is an electronic component that monitors the rotational speed of the transmission or wheels and sends this data to the engine control unit (ECU) and instrument cluster. This information is critical for accurate speedometer readings, transmission shift timing, cruise control operation, and overall engine management. Typically constructed with a magnetic or hall-effect sensor design, the VSS is built for durability and precise signal output under varying driving conditions.

• Inaccurate or non-functioning speedometer – caused by faulty or missing speed signals.
• Erratic transmission shifting – due to incorrect data being sent to the ECU.
• Illuminated check engine light (CEL) or ABS warning light – often accompanied by diagnostic trouble codes related to speed sensor failure.

About Genuine Volvo

The original parts used by Volvo to build your car are available as replacement parts under the “Genuine Volvo” brand. Manufactured under the direction of Volvo, expect excellent quality and a premium price since these parts are exclusively available through the Volvo Dealership network.

You may not realize this, but the parts that make up your Volvo are not necessarily manufactured by Volvo. No cause for concern, as Volvo designs the part, hires a manufacturer, and ensures its quality to you. In fact, many of these manufacturers have been making parts for Volvo for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Volvo parts box and find an OEM branded part inside, simply with the addition of a Volvo logo.

Be sure to keep an eye out for OE tags on our product pages to quickly identify parts coming direct from OE manufacturers. That extra bit of insight could save you some serious money while shopping! Refer to our OE Academy for further information regarding the OE/OEM tags throughout the site.
