DTC P0500: Vehicle Speed Sensor [12/2015 - 08/2016]: Description
WARNING: This page is about a different car, the 2016 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
The wheel speed sensors monitor the wheel rotation speed and send signals to the skid control ECU. The skid control ECU converts the wheel speed signal into a 4-pulse signal and transmits it to the ECM via the combination meter assembly. The ECM determines the vehicle speed based on the frequency of the pulse signal.
HINT:
- Various systems use the vehicle speed signal distributed from the combination meter assembly. Check all the components possibly related to speed signal.
- A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter assembly. The signal is changed to a pulse signal at the transistor in the combination meter assembly. Each ECU controls the respective system based on the pulse signal.
- If a short occurs in any of the ECUs or in the wire harness connected to an ECU, all systems in the wiring diagram below will not operate normally.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0500 | While vehicle being driven, no vehicle speed sensor signal transmitted to ECM (1 trip detection logic). |
