DTC P0720 VEHICLE SPEED SENSOR·A/T (REVOLUTION SENSOR)
Revision: June 20062007 Versa
TCM terminal data are reference values, measured between each terminal and ground.
Diagnostic ProcedureUCS005O0
1. CHECK INPUT SIGNAL
With CONSULT-II
1. Start engine.
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Read out the value of “VHCL/S SE-A/T” while driving.
Check the value changes according to driving speed.
OK or NG
OK >> GO TO 8.
NG >> GO TO 2.
2. CHECK REVOLUTION SENSOR
With CONSULT-II
1. Start engine.
2. Check power supply to revolution sensor by voltage between TCM connector terminals. Refer to AT-183,
"Wiring Diagram — AT — MAIN" and AT-109, "Wiring Diagram — AT — VSSA/T" .
3. If OK, check the pulse when vehicle cruises.
OK or NG
OK >> GO TO 8.
NG >> GO TO 3.
