Vehicle Speed Sensor×MTR
DESCRIPTION
The vehicle speed sensor×MTR is built into the speedometer
assembly. The sensor functions as an auxiliary device to the revo-
lution sensor when it is malfunctioning. The TCM will then use a
signal sent from the vehicle speed sensor×MTR.

: VHCL SPEED SEN×MTR TCM does not receive the proper volt-
age signal from the sensor.I
