DTC P0500 Vehicle Speed Sensor Malfunction: Description

The speed sensor for the skid control ECU detects wheel speed and sends appropriate signals to the skid control ECU.

The skid control ECU converts these wheel speed signals into 4-pulse signals and outputs them to the hybrid vehicle control ECU via the combination meter.

The hybrid vehicle control ECU determines vehicle speed based on the frequency of these pulse signals.
