P1721 VEHICLE SPEED SIGNAL

P1721 VEHICLE SPEED SIGNAL

Description

INFOID:0000000005274094

The vehicle speed signal is transmitted from combination meter to TCM by CAN communication line. The sig-
nal functions as an auxiliary device to the output speed sensor when it is malfunctioning. The TCM will then
use the vehicle speed signal.

CONSULT-III Reference Value in Data Monitor Mode

INFOID:0000000005274095

On Board Diagnosis Logic

INFOID:0000000005274096

• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “P1721” with CONSULT-III is detected when TCM does not receive the proper vehi-

cle speed signal (input by CAN communication) from combination meter.

Possible Cause

INFOID:0000000005274097

Harness or connectors
(The sensor circuit is open or shorted.)

DTC Confirmation Procedure

INFOID:0000000005274098
