P1721 VEHICLE SPEED SENSOR MTR
Description
INFOID:0000000003130525
The vehicle speed sensor·MTR signal is transmitted from unified meter and A/C amp. to TCM by CAN commu-
nication line. The signal functions as an auxiliary device to the revolution sensor when it is malfunctioning. The
TCM will then use the vehicle speed sensor·MTR signal.
