SAT357H
DescriptionNJAT0038The revolution sensor detects the revolution of the idler gear park-
ing pawl lock gear and emits a pulse signal. The pulse signal is sent
to the TCM which converts it into vehicle speed.

DescriptionNJAT0079The 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.
