2011 Toyota Landcruiser V8-5.7L (3UR-FE)SECTION Cruise Control System




CRUISE CONTROL: CRUISE CONTROL SYSTEM: P0500: Vehicle Speed Sensor Malfunction
P0500 - Vehicle Speed Sensor Malfunction

DESCRIPTION

The speed sensor detects the wheel speed and sends the appropriate signals to the master cylinder solenoid (skid control ECU). The master cylinder solenoid (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.
