OEM Transmission Speed Sensor for 1996-2004 Nissan Pathfinder models equipped with 4WD.

The Transmission Speed Sensor, also known as the vehicle speed sensor (VSS) or output speed sensor (OSS), is an essential component of a vehicle's transmission system. It is responsible for measuring the rotational speed of the transmission output shaft and providing this information to the vehicle's engine control module (ECM) or transmission control module (TCM). This data is crucial for proper shifting of gears and other transmission functions.

Here are some signs that the transmission speed sensor may need to be replaced:

• Malfunctioning speedometer: A faulty speed sensor can cause inaccurate or erratic readings on the speedometer. You may notice that the speedometer needle jumps around, stays at zero, or doesn't move at all.
• Erratic shifting: The TCM relies on the speed sensor input to determine when to shift gears. If the sensor is faulty, it can provide incorrect data, resulting in erratic or delayed shifting. You may experience rough shifting, harsh engagement, or the transmission getting stuck in a specific gear.
• Cruise control issues: The speed sensor is also utilized by the cruise control system to maintain a constant speed. If the sensor is faulty, it can cause the cruise control to work intermittently or not engage at all.
• Check engine light: A malfunctioning speed sensor can trigger the check engine light to illuminate. The vehicle's onboard diagnostic system may generate a trouble code related to the speed sensor, such as a P0500 or P0720 code.

Additionally, if the sensor is damaged or shows signs of physical wear, such as corrosion or broken wiring, it should be replaced.
