Walker Products 240-1201 Vehicle Speed Sensor

The Walker Products 240-1201 is a direct-fit Vehicle Speed Sensor (VSS) engineered to restore accurate speed monitoring to your vehicle's drivetrain and engine management system. Designed as a reliable OEM-replacement part, this sensor delivers the precise electrical signal data your vehicle's powertrain control module (PCM/ECU) depends on for proper operation.

How It Works:

The vehicle speed sensor generates electrical pulses by way of a magnet spinning a sensor coil. As vehicle speed increases, the frequency of these pulses increases proportionally, giving the PCM a continuous real-time speed reading. These sensors are typically mounted at the transmission, differential, or wheel hub.

Symptoms of a Failing Speed Sensor:

• Erratic or non-functional speedometer
• Harsh, delayed, or incorrect automatic transmission shifting
• Loss of cruise control function
• Engine hesitation or surging
• Illuminated Check Engine Light (CEL)

Key Features:

• Engineered to meet or exceed OEM fit, form, and function standards
• Manufactured using high-quality components for long-term durability
• Undergoes rigorous fit, form, and function quality control testing
• Direct plug-and-play replacement — no modifications required
• Produced by Walker Products, an ISO 9001 / IATF 16949 certified manufacturer
