CKP SENSOR PEAK VOLTAGE
(NSS250S)
USING THE TEST PROBE
• Check all system connections before performing
this inspection. If the system is disconnected,
incorrect peak voltage might be measured.
• Check that the cylinder compression is normal
and the spark plug is installed correctly.
Place the scooter on its center stand.
Disconnect the ECM 33P (Black) connector (page 6-
