P0720 VEHICLE SPEED SENSOR A/T (REVOLUTION SENSOR)

Description

INFOID:0000000003130487

The revolution sensor detects the revolution of the parking gear and emits a pulse signal. The pulse signal is
transmitted to the TCM which converts it into vehicle speed.

DTC CONFIRMATION PROCEDURE

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. Then wait at least 10 seconds before performing the next test.

1.

CHECK REVOLUTION SENSOR AND VEHICLE SPEED SENSOR MTR

With CONSULT-III

1.

Start the engine.

2.

Select “Data Monitor” mode for “TRANSMISSION”.

3.

Drive vehicle and check for an increase of “VHCL/S SE-A/T” value in response to “VHCL/S SE-MTR”
value.

Are “VHCL/S SE-A/T” and “VHCL/S SE-MTR” values correct?

YES

>> GO TO 2.

NO

>> Go to

TM-54, "Diagnosis Procedure"

.

2.

CHECK DTC DETECTION 1

With CONSULT-III

1.

Select “Data Monitor” mode for “TRANSMISSION”.

2.

Drive vehicle and maintain the following conditions for at least 5 consecutive seconds.
