Standard Motor Products SC669 Vehicle Speed Sensor - VSS 2-Terminal

The Standard Motor Products SC669 is a direct-fit replacement Vehicle Speed Sensor (VSS) engineered to restore accurate speed signal output to your vehicle's engine and transmission control systems. Sold individually, this 2-terminal, bolt-on sensor features a rectangular connector with blade-style male terminals for a precise OE-match fit.

The VSS plays a critical role in modern vehicle operation. Beyond simply measuring wheel speed, it feeds data to the Engine Control Module (ECM) to influence fuel delivery, ignition timing, idle-air control valve operation, and evaporative canister purge cycles. In automatic transmissions, VSS data governs torque converter clutch engagement and electronic shift point determination — making a properly functioning speed sensor essential for both performance and fuel economy.
