DTC P1721 VEHICLE SPEED SENSOR MTR
PFP:24814
Description
NCS000EM
The vehicle speed sensor·MTR signal is transmitted from combination meter to TCM by CAN communication
line. The signal functions as an auxiliary device to the revolution sensor when it is malfunctioning. The TCM
will then use the vehicle speed sensor·MTR signal.
CONSULT-II Reference Value
NCS000EN
On Board Diagnosis Logic
NCS000EO
●
This is not an OBD-II self-diagnostic item.
●
Diagnostic trouble code “P1721 VEH SPD SE/CIR-MTR” with CONSULT-II is detected when TCM does
not receive the proper vehicle speed sensor MTR signal (input by CAN communication) from combination
meter.
Possible Cause
NCS000EP
Harness or connectors.
(Sensor circuit is open or shorted.)
DTC Confirmation Procedure
NCS000EQ
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-II
1.
Turn ignition switch ON.
2.
Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3.
Touch “START”.
4.
Start engine and maintain the following conditions for at least 5
consecutive seconds.
ACCELE POSI: 1.0/8 or less
VHCL/S SE-MTR: 30 km/h (17 MPH) or more
