DTC P0720 VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)PFP:32702
DescriptionUCS005N U
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-II Reference ValueUCS005NV
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS005NW

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0720 VHCL SPEED SEN-AT” with CONSULT-II or 1st judgement flicker without
CONSULT-II is detected when TCM does not receive the proper voltage signal from the sensor.
