DTC P0500-31: Vehicle Speed Sensor "A" No Signal [10/2014 - ]: Description

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

The speed sensors detect the wheel speed and send the appropriate signals to the skid control ECU. The skid control ECU converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM via the combination meter. The ECM determines the vehicle speed based on the frequency of these pulse signals.
