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.
