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
