P1715 INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)

P1715 INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)

Description

INFOID:0000000001089480

ECM receives primary speed sensor signal from TCM through CAN communication line. ECM uses this signal
for engine control.

DTC Logic

INFOID:0000000001089481

DTC DETECTION LOGIC

NOTE:
• If DTC P1715 is displayed with DTC U1001 first perform the trouble diagnosis for DTC U1001. Refer

to 

EC-740, "DTC Logic"

.

• If DTC P1715 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer

to 

EC-741, "DTC Logic"

.

• If DTC P1715 is displayed with DTC P0335, first perform the trouble diagnosis for DTC P0335. Refer

to 

EC-809, "DTC Logic"

.

• If DTC P1715 is displayed with DTC P0340, first perform the trouble diagnosis for DTC P0340. Refer

to 

EC-813, "DTC Logic"

.

• If DTC P1715 is displayed with DTC P0605, first perform the trouble diagnosis for DTC P0605. Refer

to 

EC-827, "DTC Logic"

.

EC-895, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000001089482

1.

CHECK DTC WITH TCM

Check DTC with TCM. Refer to 

TM-214, "Diagnosis Description"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Perform trouble shooting relevant to DTC indicated.

2.

REPLACE TCM

Replace TCM.

>> INSPECTION END

DTC No.

Trouble diagnosis name

DTC detecting condition

Possible cause

P1715

Input speed sensor
(Primary speed sensor)
(TCM output)

Primary speed sensor signal is different 
from the theoretical value calculated by 
ECM from secondary speed sensor signal 
and engine rpm signal.

• Harness or connectors

(The CAN communication line is open or short-
ed)

• Harness or connectors

(Primary speed sensor circuit is open or short-
ed)
