VEHICLE SPEED SENSOR MTR

VEHICLE SPEED SENSOR MTRPFP:24814
DescriptionBCS0010M
Vehicle speed sensor·MTR is built into speedometer assembly. Sensor functions is an auxiliary device to the
revolution sensor when it is malfunctioning. TCM will then use a signal sent from vehicle speed sensor·MTR.
CONSULT-II Reference ValueBCS0010N
On Board Diagnosis LogicBCS0010O
Diagnostic trouble code “VHCL SPEED SEN-MTR” with CONSULT-II or 2nd judgement flicker without CON-
SULT-II is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseBCS0010P

Harness or connector
(Sensor circuit is open or shorted.)

Vehicle speed sensor
DTC Confirmation ProcedureBCS0010Q
CAUTION:

Always drive vehicle at a safe speed.

If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait
at least 10 seconds before continuing.
After the repair, perform the following procedure to confirm that the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Start engine and accelerate vehicle from 0 to 25 km/h (0 to 16
MPH).
4. If DTC is detected, go to AT- 8 8 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever position: “D” position
Vehicle speed: Higher than 25 km/h (16 MPH)
3. Perform self-diagnosis. Refer to AT- 7 6 , "
Diagnostic Procedure Without CONSULT-II" .
4. If the check result is NG, go to AT- 8 8 , "
Diagnostic Procedure" .
