Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
: Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.)

DTC P1715 INPUT SPEED SENSOR (TURBINE REVOLUTION SENSOR)PFP:31935
DescriptionNBS005NA
ECM receives turbine revolution sensor signal from TCM through CAN communication line. ECM uses this
signal for engine control.
CONSULT-II Reference Value in Data Monitor ModeNBS005NB
Specification data are reference values.
On Board Diagnosis LogicNBS005NC
NOTE:
If DTC P1715 is displayed with DTC U1000, U1001 first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-886, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
If DTC P1715 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010.
Refer to EC-889, "
DTC U1010 CAN COMMUNICATION" .
If DTC P1715 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605.
Refer to EC-1215, "
DTC P0605 ECM" .
If DTC P1715 is displayed with DTC P0335, first perform the trouble diagnosis for DTC P0335.
Refer to EC-1099, "
DTC P0335 CKP SENSOR (POS)" .
If DTC P1715 is displayed with DTC P0340, first perform the trouble diagnosis for DTC P0340.
Refer to EC-1106, "
DTC P0340 CAMSHAFT POSITION (CMP) SENSOR (PHASE)" .
The MIL will not lights up for this diagnosis.
