SEF080X
Component DescriptionNJEC0272The vehicle speed sensor is installed in the transaxle. It contains a
pulse generator which provides a vehicle speed signal to the
speedometer. The speedometer then sends a signal to the ECM.
ECM Terminals and Reference ValueNJEC0273Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

DTC Confirmation ProcedureNJEC0275CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch ªOFFº and wait at least 9 seconds
before conducting the next test.
TESTING CONDITION:
This procedure may be conducted with the drive wheels lifted
in the shop or by driving the vehicle. If a road test is expected
to be easier, it is unnecessary to lift the vehicle.

With CONSULT-II
1) Start engine
2) Read ªVHCL SPEED SEº in ªDATA MONITORº mode with
CONSULT-II. The vehicle speed on CONSULT-II should
exceed 10 km/h (6 MPH) when rotating wheels with suitable
gear position.
3) If NG, go to ªDiagnostic Procedureº, EC-312.
If OK, go to following step.
4) Select ªDATA MONITORº mode with CONSULT-II.
5) Warm engine up to normal operating temperature.
6) Maintain the following conditions for at least 10 consecutive
seconds.
ENG SPEED 2,600 - 4,000 rpm (M/T)
2,600 - 3,000 rpm (A/T)
COOLAN TEMP/S More than 70ÉC (158ÉF)

7) If 1st trip DTC is detected, go to ªDiagnostic Procedureº,
EC-312.
With GST
Follow the procedure ªWith CONSULT-IIº above.
SEF607Y
Without CONSULT-II
1) Lift up drive wheels.
2) Start engine.
3) Read the voltage signal between ECM terminal 86 (Vehicle
speed sensor signal) and ground with oscilloscope.
4) Verify that the oscilloscope screen shows the signal wave as
shown in the figure.
5) If NG, go to ªDiagnostic Procedureº, EC-312.

Diagnostic ProcedureNJEC0278
1 CHECK INPUT SIGNAL CIRCUIT
1. Turn ignition switch ªOFFº.
2. Disconnect ECM harness connector and combination meter harness connector.
3. Check harness continuity between ECM terminal 86 and meter terminal 4.
Refer to wiring diagram.
Continuity should exist.
4. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 3.
NG©GO TO 2.
2 DETECT MALFUNCTIONING PART
Check the following.
+Harness connectors M63, F102
+Harness for open or short between ECM and combination meter
©Repair open circuit or short to ground or short to power in harness or connectors.
3 CHECK SPEEDOMETER FUNCTION
Make sure that speedometer functions properly.
OK or NG
OK©GO TO 5.
NG©GO TO 4.
4 CHECK SPEEDOMETER CIRCUIT
Check the following.
+Harness connectors M63, F102
+Harness connectors M169, F113
+Harness for open or short between combination meter and vehicle speed sensor
OK©Check combination meter and vehicle speed sensor. Refer to EL-89, ªMETERS AND
GAUGESº.
NG©Repair open circuit or short to ground or short to power in harness or connectors.
5 CHECK INTERMITTENT INCIDENT
Perform ªTROUBLE DIAGNOSIS FOR INTERMITTENT INCIDENTº, EC-144.
