P1721 VEHICLE SPEED SENSOR MTR
P1721 VEHICLE SPEED SENSOR MTR
Description
INFOID:0000000000957064
The vehicle speed sensor·MTR signal is transmitted from unified meter and A/C amp. combination meter to
TCM by CAN communication 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.
DTC Logic
