Walker Products 240-1039 Vehicle Speed Sensor

The Walker Products 240-1039 is a direct-fit replacement Vehicle Speed Sensor (VSS) engineered to restore accurate speed detection and reliable powertrain communication. The sensor monitors the rotational speed of transmission components and relays real-time data to the Powertrain Control Module (PCM) or Engine Control Unit (ECU), keeping your vehicle's systems operating as intended.

As vehicle speed increases, the frequency of the sensor's output pulse increases proportionally, providing the ECU with the precise signal it needs to manage speedometer accuracy, cruise control operation, and automatic transmission shift quality.

Common Symptoms of a Failing Vehicle Speed Sensor:

• Erratic or non-functional speedometer
• Loss of cruise control function
• Improper or harsh automatic transmission shifting
• Engine hesitation or surging

Key Features:
