Standard Motor Products SC633 Vehicle Speed Sensor

The Standard Motor Products SC633 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. As a critical input device, the VSS monitors transmission or transaxle output shaft speed and delivers that data to the Engine Control Module (ECM).

Key Features:

• Direct OEM replacement design for reliable, plug-and-play installation
• Manufactured to meet or exceed original equipment specifications
• Undergoes environmental, endurance, and 100% end-of-line testing for signal amplitude and polarity
• Engineered for precision performance, durability, and long service life
• Complete control of the manufacturing process from componentry to finished product

How the Vehicle Speed Sensor Works:

• Measures transmission or transaxle output shaft speed and reports it to the ECM
• ECM uses VSS data to refine ignition timing, air/fuel ratio, and transmission shift points
• Regulates torque converter clutch operation on automatic transmissions
• Influences idle-air control valve operation and canister-purge cycles
• Supports OBD-II diagnostic routines and cruise control operation

Backed by Standard Motor Products' century-long reputation for quality, the SC633 Vehicle Speed Sensor is built to deliver the consistent, accurate signal output your vehicle's control systems depend on.
