DTC P1723 CVT SPEED SENSOR FUNCTIONPFP:31907
DescriptionBCS001L5
The vehicle speed sensor CVT [output speed sensor (secondary speed sensor)] detects the revolution of the
idler gear parking pawl lock gear and generates a pulse signal. The pulse signal is sent to the TCM, which
converts it into vehicle speed.
The input speed sensor (primary speed sensor) detects the primary pulley revolution speed and sends a sig-
nal to the TCM.
On Board Diagnosis LogicBCS001L6
Diagnostic trouble code “P1723 CVT SPD SEN/FNCTN” with CONSULT-II is detected when there is a great
difference between the vehicle speed signal and the secondary speed sensor signal.
CAUTION:
One of the “P0720 VEH SPD SEN/CIR AT”, the “P0715 INPUT SPD SEN/CIRC” or the “P0725 ENGINE
SPEED SIG” is displayed with the DTC at the same time.
Possible CauseBCS001L7
Harness or connectors
(Sensor circuit is open or shorted.)
Output speed sensor (Secondary speed sensor)
Input speed sensor (Primary speed sensor)
Engine speed signal system
DTC Confirmation ProcedureBCS001L8
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, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
2. Start engine and maintain the following conditions for at least 5
consecutive seconds.
VEHICLE SPEED: 10 km/h (6 MPH) or more
ACC PEDAL OPEN: More than 1.0/8
RANGE: “D” position
ENG SPEED: 450 rpm or more
Driving location: Driving the vehicle uphill (increased
engine load) will help maintain the driving conditions
required for this test.
3. If DTC is detected, go to CVT-144, "
