How to solve the Dongfeng Tianlong VSS malfunction?

[JasmineLee]

VSS malfunction means the speed sensor is damaged and needs replacement. Below is detailed information about it: 1. Introduction 1: When VSS malfunctions, the vehicle speed information cannot be transmitted to the instrument panel via the CAN bus, resulting in missing or invalid speed information, which may cause unstable engine idling. 2. Introduction 2: During vehicle start-up or deceleration to a stop while driving, momentary stalling or engine shutdown may occur, accompanied by reduced engine acceleration performance and other abnormalities. 3. Introduction 3: The Vehicle Speed Sensor (VSS) transmits the car's speed as an electrical signal to the Electronic Control Unit (ECU), serving as a reference for controlling engine idling, automatic transmission shifting, torque converter lock-up, engine cooling fan operation, cruise control, and other functions.
