What does the VSS fault of Dongfeng Tianlong mean?
1 Answers
vss fault refers to the vehicle speed sensor fault, which causes abnormal speedometer indication. When the vehicle speed sensor fails, symptoms may include unstable engine idle speed, momentary stalling or engine shutdown during deceleration when starting or driving, reduced engine acceleration performance, deviation in the speed display on the instrument panel, and illumination of the engine fault light. Here is more information about VSS: 1. Definition of VSS: "VSS" stands for vehicle speed sensor. The function of the vehicle speed sensor (VSS) is to transmit the vehicle's speed in the form of an electrical signal to the electronic control unit (ECU), serving as a reference for controlling engine idle speed, automatic transmission shifting, torque converter lock-up, engine cooling fan operation, cruise control, and other functions. 2. Installation location of VSS: The vehicle speed sensor is usually installed inside the drive axle housing or transmission housing. The signal wire of the vehicle speed sensor is typically enclosed in a shielded jacket to eliminate electromagnetic and radio frequency interference caused by high-voltage ignition wires, car phones, or other electronic devices, ensuring uninterrupted electronic communication and preventing degraded driving performance or other issues.
