Standard Motor Products SC294 Vehicle Speed Sensor

The Standard Motor Products SC294 is a direct-fit replacement Vehicle Speed Sensor (VSS) engineered to restore accurate speed signal output to your vehicle's powertrain control systems. The VSS measures transmission or transaxle output shaft speed and delivers that data to the Engine Control Module (ECM) to optimize critical vehicle functions.

How the Vehicle Speed Sensor Works:

The VSS monitors transmission output speed and feeds real-time data to the ECM. This signal influences a wide range of vehicle systems, making it one of the most critical sensors on the vehicle. With OBD-II vehicles, vehicle speed data is integrated into overall engine operating strategy — affecting fuel delivery, ignition timing, idle-air control valve operation, and evaporative emission canister-purge cycles. For automatic transmissions, the VSS governs shift points, torque converter clutch engagement, and overall transmission performance.

Key Features:

• Direct OE replacement for precise fit and function
• Measures transmission/transaxle output shaft speed for accurate ECM data
• Influences ignition timing, air/fuel ratio, and transmission shift points
• Controls torque converter clutch operation in automatic transmissions
• Supports electronically shifted transmission shift point determination
• Environmentally and endurance tested for signal amplitude and polarity
• 100% end-of-line tested for consistent reliability and performance
• Corrosion-resistant construction to withstand underhood conditions
• Manufactured by Standard Motor Products — a leading OE-level supplier to the automotive aftermarket

The Standard Motor Products SC294 Vehicle Speed Sensor is built to OE specifications and undergoes rigorous testing to ensure accurate signal output right out of the box. It is an ideal replacement for a failed or malfunctioning VSS causing speedometer irregularities, transmission shift problems, or related fault codes.
