Vehicle Speed Sensor (VSS)
Models with vehicle speed sensor
The vehicle speed sensor is installed in the transaxle. It contains
a pulse generator which provides a vehicle speed signal to the
speedometer. The speedometer then sends a signal to the ECM.
Models without vehicle speed sensor
The ABS actuator and electric unit (control unit) provides a
vehicle speed signal to the speedometer. The speedometer than
sends a signal to the ECM.
Malfunction is detected when .
Check Items
(Possible Cause)
●
The almost 0 km/h (0 mph) signal from vehicle speed sen-
sor or ABS actuator and electric unit (control unit) is sent
to ECM even when vehicle is being driven.
Models with vehicle speed sensor
●
Harness or connector
(The vehicle speed sensor circuit is open or shorted.)
●

OVERALL FUNCTION CHECK
Use this procedure to check the overall function of the vehicle
speed sensor circuit. During this check, a DTC might not be
confirmed.
1)
Jack up drive wheels.
2)
Start engine.
3)
Read vehicle speed sensor signal in “DATA MONI-
TOR” mode with CONSULT-II.
The vehicle speed on CONSULT-II should be able to
exceed 10 km/h (6 mph) when rotating wheels with
suitable gear position.

1)
Jack up drive wheels.
2)
Start engine.
3)
Rotate drive wheel by hand.
4)
Check voltage between ECM connector terminal
417
and ground with voltage tester.
Voltage should vary between approx. 0 - 0.6V.
