Product Details
The Honda OEM Vehicle Speed Sensor (VSS) is a genuine factory replacement designed for the 2002-2004 Acura RSX Type-S and 2004-2005 Honda Civic Si (EP3). This essential electronic sensor monitors transmission output speed and provides the vehicle's ECU and instrument cluster with accurate vehicle speed information.
Originally installed on select K-series manual transmissions, this genuine Honda speed sensor plays an important role in proper speedometer operation, engine management, and other vehicle systems that rely on vehicle speed data.
Over time, the original vehicle speed sensor can fail due to internal electronic wear, damaged wiring connections, or exposure to heat and vibration. A malfunctioning sensor may cause an inoperative or erratic speedometer, intermittent vehicle speed readings, cruise control problems, or diagnostic trouble codes related to the vehicle speed signal.
Manufactured to Honda's original equipment specifications, this genuine OEM replacement is designed to restore accurate speed signal transmission without the uncertainty of aftermarket sensor compatibility.
Whether you're repairing your RSX Type-S, maintaining your EP3 Civic Si, or completing a K-series engine and transmission swap, this genuine Honda Vehicle Speed Sensor provides factory-quality performance and dependable operation.
