P0720 OUTPUT SPEED SENSOR

Description

INFOID:0000000005274026

The output speed sensor detects the revolution of the parking 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:0000000005274027

On Board Diagnosis Logic

INFOID:0000000005274028

• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0720” with CONSULT-III or 1st judgment flicker without CONSULT-III is detected

under the following conditions.

- When TCM does not receive the proper voltage signal from the sensor.
- After ignition switch is turned “ON”, irregular signal input from vehicle speed signal before the vehicle starts

moving.

Possible Cause

INFOID:0000000005274029

• Harness or connectors

(The sensor circuit is open or shorted.)

• Output speed sensor
• Vehicle speed signal

DTC Confirmation Procedure

INFOID:0000000005274030

CAUTION:

• Always drive vehicle at a safe speed.
• Be careful not to rev engine into the red zone on the tachometer.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 10 seconds before performing the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.

 WITH CONSULT-III

1.

Turn ignition switch “ON”. (Do not start engine.)

2.

Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

3.

Drive vehicle and check for an increase of “VHCL/S SE-A/T” value in response to “VHCL/S SE-MTR”
value.
If the check result is NG, go to 

TM-168, "Diagnosis Procedure"

.

If the check result is OK, go to following step.

4.

Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.

5.

Start engine and maintain the following conditions for at least 5 consecutive seconds.
VHCL/S SE-A/T: 30 km/h (19 MPH) or more
ACCELE 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 

TM-168, "Diagnosis Procedure"

.

If the check result is OK, go to following step.

6.

Maintain the following conditions for at least 5 consecutive seconds.
ENGINE SPEED: 3,500 rpm or more
ACCELE 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 

TM-168, "Diagnosis Procedure"

.
