OPERATION
l
The vehicle speed sensor which is located in the speedometer converts the vehicle speed into a
pulse signal and inputs it to the engine control module, which then provides the idle speed control,
etc. based on this signal.
l
The vehicle speed sensor generates the vehicle speed signal by repeatedly opening and closing
between the voltage of about 5 V applied from the engine control module and ground using a reed
switch.
TROUBLESHOOTING HINTS
If there is an open or short circuit in the vehicle speed sensor signal circuit, the engine may stall when
the vehicle is decelerated to stop.
HARNESS INSPECTION
Check the vehicle speed sensor
output circuit for continuity.
