DTC P0500: Vehicle Speed Sensor "A"; DTC P0502: Vehicle Speed Sensor "A" Circuit Low; DTC P0503: Vehicle Speed Sensor "A" Intermittent / Erratic / High: Description
WARNING: This page is about a different car, the 2008 Lexus IS F. However, it is still accessible from the selected car via links, so may be relevant.
The speed sensor (SP2) detects the output shaft rotation speed and sends it to the TCM.
Based on the speed sensor (NT) signal and the speed sensor (SP2) signal, the TCM controls engine torque and shift timing
