VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)

VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)PFP:32702
DescriptionBCS0010F
The revolution sensor detects the revolution of the idler gear parking pawl lock gear and emits a pulse signal.
The pulse signal is sent to the TCM which converts it into vehicle speed.
CONSULT-II Reference ValueBCS0010G
On Board Diagnosis LogicBCS0010H
Diagnostic trouble code “VHCL SPEED SEN-A/T” with CONSULT-II or 1st judgement flicker without CON-
SULT-II is detected when TCM does not receive the proper voltage signal from the sensor.
Possible CauseBCS0010I

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

Revolution sensor
DTC Confirmation ProcedureBCS0010J
CAUTION:

Always drive vehicle at a safe speed.

Be careful not to rev engine into the red zone on the tachometer.

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 the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON and select “DATA MONITOR” mode for
“A/T” with CONSULT-II.
2. Drive vehicle and check for an increase of “VHCL/S SE-MTR”
value.
If the check result is NG, go to AT- 8 8 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
3. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
4. Start engine and maintain the following conditions for at least 5
consecutive seconds.
VEHICLE SPEED: 30 km/h (19 MPH) or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
If the check result is NG, go to AT- 8 3 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 5 consecutive seconds.
ENGINE SPEED: 3,500 rpm or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
Driving location: Driving the vehicle uphill (increased engine load) will help maintain the driving
conditions required for this test.
6. If DTC is detected, go to AT- 8 3 , "
Diagnostic Procedure" .

Diagnostic ProcedureBCS0010L
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-A/T” while driving.
Check the value changes according to driving speed.
OK or NG
OK >> GO TO 8.
NG >> GO TO 2.
2. CHECK REVOLUTION SENSOR
With CONSULT-II
1. Start engine.
2. Check power supply to revolution sensor by voltage between TCM connector terminals. Refer to AT- 1 5 8 ,
"Wiring Diagram — AT — MAIN" .
3. If OK check the pulse when vehicle cruises.
OK or NG
OK >> GO TO 8.
NG >> GO TO 3.

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

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
