DTC VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionECS004TM
The vehicle speed sensor·MTR is built into the speedometer assem-
bly. The sensor functions as an auxiliary device to the revolution sen-
sor when it is malfunctioning. The TCM will then use a signal sent
from the vehicle speed sensor·MTR.
TCM TERMINALS AND REFERENCE VALUE
