Vehicle Speed Sensor Malfunction
CIRCUIT DESCRIPTION
The No.1 vehicle speed sensor outputs a 4
−
pulse signal for every revolution of the rotor shaft, which is ro-
tated by the transmission output shaft via the driven gear. After this signal is converted into a more precise
rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted
to the ECM. The ECM determines the vehicle speed based on the frequency of these pluse signals.
DTC No.

ECM
MONITOR DESCRIPTION
The ECM assumes that the vehicle is driven when over 30 sec. have passed since the park/neutral position
switch was turned OFF. If there is no signal from the vehicle speed sensor with these conditions satisfied,
the ECM concludes that the vehicle speed sensor is malfunctioning. The ECM will turn on the MIL and a DTC
will be set.
