CIRCUIT INSPECTION
DTC P0500
CIRCUIT DESCRIPTION
The vehicle speed sensor outputs a 4–pulse signal for every revolution of the rotor shaft, which is rotated
by the transmission output shaft via the driven gear. After this signal is converted into a more precise rectan-
gular wave form by the wave form 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.
