Vehicle Speed Sensor: Testing and Inspection
Diagnosis Of Vehicle Speed Sensor
Fault recognition of vehicle speed is performed during fuel cut-off.
A signal fault is detected if:
- the condition fuel cut-off is valid for the time period threshold,
- the engine speed is between two given thresholds,
- simultaneously the vehicle speed is lower than threshold and,
- engine temperature is greater than threshold.
