Component DescriptionNCEC0327The crankshaft position sensor (OBD) is located on the transmis-
sion housing facing the gear teeth (cogs) of the flywheel or drive
plate. It detects the fluctuation of the engine revolution.
The sensor consists of a permanent magnet, core and coil.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
This sensor is not used to control the engine system.
It is used only for the on board diagnosis.
ECM Terminals and Reference ValueNCEC0328Specification data are reference values and are measured between each terminal and 48 (ECM ground).

DTC Confirmation ProcedureNCEC0330NOTE:
If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch ªOFFº and wait at least 5 seconds
before conducting the next test.
With CONSULT-II
1) Turn ignition switch ªONº and select ªDATA MONITORº mode
with CONSULT-II.
2) Start engine and run it for at least 4 minutes at idle speed.
3) If 1st trip DTC is detected, go to ªDiagnostic Procedureº, EC-
SR-293.
With GST
Follow the procedure ªWith CONSULT-IIº above.

Diagnostic ProcedureNCEC0332
1 RETIGHTEN GROUND SCREWS
1. Turn ignition switch ªOFFº.
2. Loosen and retighten engine ground screws.
©GO TO 2.
2 CHECK INPUT SIGNAL CIRCUIT
1. Disconnect crankshaft position sensor (OBD) and ECM harness connectors.
SEF226X2. Check continuity between ECM terminal 65 and crankshaft position sensor (OBD) harness connector terminal 1.
Refer to wiring diagram.
Continuity should exist.
3. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 4.
NG©GO TO 3.
3 DETECT MALFUNCTIONING PART
Check the harness for open or short between crankshaft position sensor (OBD) and ECM.
©Repair open circuit or short to ground or short to power in harness or connectors.
4 CHECK GROUND CIRCUIT
1. Reconnect ECM harness connectors.
2. Check harness continuity between crankshaft position sensor harness connector terminal 2 and engine ground.
Refer to wiring diagram.
Continuity should exist.
3. Also check harness for short to ground and short to power.
OK or NG
OK©GO TO 6.
NG©GO TO 5.
5 DETECT MALFUNCTIONING PART
Check the following.
IHarness for open or short between crankshaft position sensor (OBD) and ECM
IHarness for open or short between crankshaft position sensor (OBD) and TCM (Transmission control module)
©Repair open circuit or short to ground or short to power in harness or connectors.
