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" .

Data are reference value and are measured between each terminal and ground.
Diagnostic ProcedureBCS0010S
1. CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out the value of “VHCL/S SE-MTR” while driving.
Check the value changes according to driving speed.
Without CONSULT-II
1. Start engine.
2. Check voltage between TCM connector terminal and ground.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. DETECT MALFUNCTIONING ITEM
Check the following items:

Unified meter and A/C amp. Refer to DI-27, "UNIFIED METER AND A/C AMP" .

Harness for short or open between TCM and unified meter and A/C amp.
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.

SHIFT SOLENOID VALVE A

SHIFT SOLENOID VALVE APFP:31940
DescriptionBCS00110
Shift solenoid valves A and B are turned ON or OFF by TCM in response to signals sent from PNP switch,
vehicle speed and ECM (throttle opening). Gears will then be shifted to the optimum position.
CONSULT-II Reference ValueB C S 0 0 111
On Board Diagnosis LogicBCS00112
Diagnostic trouble code “SHIFT SOLENOID/V A” with CONSULT-II or 4th judgement flicker without CON-
SULT-II is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.
Possible CauseBCS00113

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