DTC P1715 INPUT SPEED SENSOR (TURBINE REVOLUTION SENSOR)
DescriptionINFOID:0000000001702969
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 ModeINFOID:0000000001702970
Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001702971
NOTE:
•If DTC P1715 is displayed with DTC U1000, U1001 first perform the trouble diagnosis for DTC U1000,
U1001. Refer to EC-143
.
•If DTC P1715 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer
to EC-145
.
•If DTC P1715 is displayed with DTC P0335, first perform the trouble diagnosis for DTC P0335. Refer
to EC-295
.
•If DTC P1715 is displayed with DTC P0340 first perform the trouble diagnosis for DTC P0340.
Refer to EC-302
.
•If DTC P1715 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer
to EC-397

Diagnosis ProcedureINFOID:0000000001702990
1.CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT-I
1. Turn ignition switch OFF.
2. Check voltage between ECM terminal 15 and ground with CON-
SULT-II or tester.
OK or NG
OK >> GO TO 5.
NG >> GO TO 2.
2.CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT-II
1. Disconnect ECM harness connector.
2. Disconnect IPDM E/R harness connector E46.
3. Check continuity between ECM terminal 15 and IPDM E/R terminal 46.
Refer to Wiring Diagram.
4. Also check harness for short to ground and short to power.
