DescriptionNLEC0686The crankshaft position sensor (TDC) monitors engine speed by
means of signals from the sensing plate (with three protrusions)
installed to the crankshaft pulley. The datum signal output is
detected at ATDC 10É and sent to the ECM. The sensor signal is
used for fuel injection control and fuel injection timing control.
CONSULT-II Reference Value in Data Monitor
Mode
NLEC0687Specification data are reference values.
MONITOR ITEM CONDITION SPECIFICATION
CKPS´RPM (TDC)+Tachometer: Connect
+Run engine and compare tachometer indication with the CON-
SULT-II value.Almost the same speed as the
CONSULT-II value.
ECM Terminals and Reference ValueNLEC0688Specification 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 ProcedureNLEC0690Before performing the following procedure, confirm that bat-
tery voltage is more than 10V.
WITH CONSULT-IINLEC0690S011) Turn ignition switch ªONº and select ªDATA MONITORº mode
with CONSULT-II.
2) Crank engine for at least 1 second.
3) Start engine and run it for at least 2 seconds at idle speed.
4) If DTC is detected, go to ªDiagnostic Procedureº, EC-1169.
WITHOUT CONSULT-IINLEC0690S021) Crank engine for at least 1 second.
2) Start engine and run it for at least 2 seconds at idle speed.
3) Turn ignition switch ªOFFº, wait at least 5 seconds and then
turn ªONº.
4) Perform ªDiagnostic Test Mode II (Self-diagnostic results)º with
ECM.
5) If DTC is detected, go to ªDiagnostic Procedureº, EC-1169.

3. Disconnect crankshaft position sensor (TDC) harness connector and ECM harness connector.
SEF387Y
4. Check harness continuity between ECM terminal 331 and crankshaft position sensor (TDC) terminal 1. Refer to Wiring
Diagram.
Continuity should exist.
5. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 2.
NG©Repair open circuit or short to ground or short to power in harness or connectors.
2 CHECK CRANKSHAFT POSITION SENSOR (TDC) INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Check harness continuity between crankshaft position sensor (TDC) terminal 2 and ECM terminal 344. Refer to Wiring
Diagram.
Continuity should exist.
2. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 3.
NG©Repair open circuit or short to ground or short to power in harness or connectors.

DescriptionNLEC0654The 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 ValueNLEC0655Specification 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.
