DTC P0500-31: Vehicle Speed Sensor "A" No Signal [11/2017 - ]: Description

WARNING: This page is about a different variant/trim than selected.

The skid control ECU converts these wheel speed signals into a pulse signal and outputs it to the ECM via the combination meter. The ECM determines the vehicle speed based on the frequency of this pulse signal.
