IGNITION SYSTEM
Turn the ignition switch OFF.
Disconnect the CKP sensor 2P (Red) connector [1] and
connect the tester probes to the connector terminals of
the CKP sensor side.
In the same manner as at the ECM 33P (Black)
connector, measure the peak voltage and compare it to
the voltage measured at the ECM 33P (Black)
connector.
– If the peak voltage measured at the ECM is
abnormal and the one measured at the CKP sensor
is normal, the wire harness has an open or short
circuit or loose connection.
– If the peak voltage of the CKP sensor side is lower
than standard value, follow the checks described in
the troubleshooting table (page 5-5).
For CKP sensor replacement (page 5-11).
Install the removed parts in the reverse order of
removal.
CKP SENSOR PEAK VOLTAGE
(NC700XD/SD)
Check the cylinder compression and check that the
spark plugs are installed correctly in the cylinder head.
Disconnect the spark plug caps (page 3-8).
Connect the ECM test harness to the PCM 33P
connectors (page 4-14).
Connect the peak voltage tester or adaptor probes to
the ECM test harness [1] terminals.
Shift the transmission into neutral.
Turn the ignition switch ON and engine stop switch " ".
Crank the engine with the starter motor and measure
the CKP sensor peak voltage.
If the peak voltage measured at the ECM test harness
is abnormal, measure the peak voltage at the CKP
sensor connector.
