Safety Warning

DTC P0500 Vehicle Speed Sensor "A": Description
The vehicle speed is detected using the No. 1 vehicle speed sensor. The No. 1 vehicle speed sensor transmits a 4-pluse signal for every revolution of the rotor shaft, which is rotated by the transaxle output shaft via the driven gear. The 4-pluse signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter. The signal is then transmitted to the ECM. The ECM determines the vehicle speed based on the frequency of the pulse signal.
| DTC No. | DTC Detection Conditions | Trouble Areas |
|---|---|---|
| P0500 | While vehicle being driven, no vehicle speed sensor signal transmitted to ECM (1 trip detection logic: Automatic transaxle) (2 trip detection logic: Manual transaxle) |
