DTC P0720 VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)

DTC P0720 VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)PFP:32702
DescriptionECS004R4
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.
On Board Diagnosis LogicECS00CTM
Possible CauseECS00CTN
Check the following items.

Harness or connector
(The sensor circuit is open or shorted.)

Revolution sensor
DTC Confirmation ProcedureECS00CTO
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 conducted, always turn ignition switch OFF and
wait at least 5 seconds before conducting the next test.
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.
SCIA0715E

THRTL POS SEN: More than 1.2V
Selector lever: D position (O/D ON)
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- 11 5 , "
Diagnostic Procedure" .
If the check result is OK, go to following step.
5. Maintain the following conditions for at least 5 consecutive seconds.
CMPS·RPM (REF): 3,500 rpm or more
THRTL POS SEN: More than 1.2V
Selector lever: D position (O/D ON)
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-II”.
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions for more than 5 sec-
onds.
Selector lever position: D position
