CRUISE CONTROL SYSTEM, Diagnostic DTC:P0500

DTC Code DTC Name
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.

DTC Code DTC Detection Condition Trouble Area
P0500 The vehicle speed signal from the vehicle speed sensor is cut for 0.14 second. or more while the cruise control is in operation.

  • Vehicle speed sensor signal circuit

  • Vehicle speed sensor

  • Combination meter
