DescriptionNLAT0038The vehicle speed sensor CVT (secondary speed sensor) detects
the revolution of the idler gear parking pawl lock gear and emits a
pulse signal. The pulse signal is sent to the TCM which converts it
into vehicle speed.

+Always drive vehicle at a safe speed.
+Be careful not to rev engine into the red zone on the
tachometer.
NOTE:
If ªDIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DUREº has been previously conducted, always turn ignition
switch ªOFFº and wait at least 5 seconds before conducting
the next test.
