Output Speed Sensor Circuit

• The vehicle speed detected 

by the output speed sensor is 
5 km/h (3MPH) or less when 
the vehicle speed transmitted 
from the combination meter 
to TCM is 20 km/h or more. 
(Only when starts after the ig-
nition switch is turned ON.)

• The vehicle speed transmit-

ted from the combination 
meter to TCM does not de-
crease despite the 36 km/h 
(23 MPH) or more of deceler-
ation in vehicle speed detect-
ed by the output speed 
sensor. when the vehicle 
speed detected by the output 
speed sensor is 36 km/h (23 
MPH) or more and the vehicle 
speed transmitted from the 
combination meter to TCM is 
24 (15 MPH) or more.

• Harness or connectors
