TROUBLE DIAGNOSIS
Judgement Self-diagnosis Code
If there is a malfunction, the lamp lights up for the time corresponding to the suspect circuit.
Erase Self-diagnosis
lIn order to make it easier to find the cause of hard-to-duplicate malfunctions, malfunction information is
stored into the control unit as necessary during use by the user. This memory is not erased no matter how
many times the ignition switch is turned ON and OFF.
lHowever, this information is erased by turning ignition switch OFF after executing self-diagnosis or by
erasing the memory using the CONSULT-II.

DTC P0720 VEHICLE SPEED SENSOR A/T (REVOLUTION SENSOR)PFP:32702
DescriptionECS00FY1
Revolution sensor detects the revolution of the idler gear parking pawl lock gear and emits a pulse signal. The
pulse signal is sent to TCM which converts it into vehicle speed.
CONSULT-II Reference ValueECS00FY2
On Board Diagnosis LogicECS00FY3
Diagnostic trouble code “P0720 VEH SPD SEN/CIR AT” with CONSULT-II or 1st judgement flicker without
CONSULT-II is detected under the following conditions.
lWhen TCM does not receive the proper voltage signal from the sensor.
lAfter ignition switch is turned ON, irregular signal input from vehicle speed sensor MTR before the vehicle
starts moving.
Possible CauseECS00FY4
lHarness or connectors
(The sensor circuit is open or shorted.)
lRevolution sensor
lVehicle speed sensor MTR
DTC Confirmation ProcedureECS00FY5
CAUTION:
lAlways drive vehicle at a safe speed.
lBe careful not to rev engine into the red zone on the tachometer.
