DTC P1721 VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionECS00FZ8
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 revolution sensor when it is malfunctioning. TCM will then
use the vehicle speed sensor MTR signal.
CONSULT-II Reference ValueECS00FZ9
On Board Diagnosis LogicECS00FZA
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 CauseECS00FZB
Harness or connectors
(The sensor circuit is open or shorted.)
DTC Confirmation ProcedureECS00FZC
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. (Do not start engine.)
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Touch “START”.
4. Start engine.
5. Drive vehicle 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
6. If DTC is detected, go toAT- 1 2 6 , "
Diagnostic Procedure".
Item name Condition Display value
VHCL/S SE-MTR During driving Approximately matches the speedometer reading.
