DTC P0720 VEHICLE SPEED SENSOR A/T (REVOLUTION SENSOR)
DescriptionINFOID:0000000001703217
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 ModeINFOID:0000000001703218
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001703219
• This is an OBD-II 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 CauseINFOID:0000000001703220
• Harness or connector
(The sensor circuit is open or shorted.)
• Revolution sensor
DTC Confirmation ProcedureINFOID:0000000001703221
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.

Diagnosis Procedure" .
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 AT-98, "
Diagnosis Procedure" .
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.
Item name Condition Display value
