DTC P0720 VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)
DTC P0720 VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)
Description
INFOID:0000000001694299
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-III Reference Value in Data Monitor Mode
INFOID:0000000001694300
Remarks: Specification data are reference values.
On Board Diagnosis Logic
INFOID:0000000001694301
• This is an OBD self-diagnostic item.
• Diagnostic trouble code “P0720 VHCL SPEED SEN-AT” with CONSULT-III or 1st judgement flicker without
CONSULT-III is detected when TCM does not receive the proper voltage signal from the sensor.
Possible Cause
INFOID:0000000001694302
• Harness or connector
(The sensor circuit is open or shorted.)
• Revolution sensor
DTC Confirmation Procedure
INFOID:0000000001694303
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-III
1.
Turn ignition switch ON and select “DATA MONITOR” mode for “A/T” with CONSULT-III.
2.
Touch “START”.
3.
Drive vehicle and check for an increase of “VHCL/S SE-MTR” value.
If the check result is NG, go to
If the check result is OK, go to following step.
4.
Select “DATA MONITOR” mode for “A/T” with CONSULT-III.
5.
Touch “START”.
6.
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
If the check result is OK, go to following step.
7.
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.
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1.
Start engine.

Diagnosis Procedure
INFOID:0000000001694305
1.
CHECK INPUT SIGNAL
With CONSULT-III
1.
Start engine.
2.
Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-III.
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-III
1.
Start engine.
2.
Check power supply to revolution sensor by voltage between TCM connector terminals.
3.
If OK, check the pulse when vehicle cruises.
OK or NG
OK
>> GO TO 8.
NG
>> GO TO 3.
3.
CHECK POWER AND SENSOR GROUND
1.
Turn ignition switch OFF.
2.
Disconnect the revolution sensor harness connector.
3.
Turn ignition switch ON. (Do not start engine.)
