P1715 INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)

P1715 INPUT SPEED SENSOR (PRIMARY SPEED SENSOR)

Description

INFOID:0000000009651233

ECM receives input speed sensor signal from TCM via the CAN communication line. ECM uses this signal for
engine control.

DTC Logic

INFOID:0000000009651234

Trouble diagnosis name

DTC detecting condition

Possible cause

P1715

Input speed sensor
(TCM output)

Input speed sensor signal is different from 
the theoretical value calculated by ECM 
from output speed sensor signal and en-
gine rpm signal.

• Harness or connectors

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

• Harness or connectors

(Input speed sensor circuit is open or shorted)
