Kawasaki Ninja Service Manual: Crankshaft Sensor Inspection

Kawasaki Ninja Service Manual / Electrical System / Ignition System / Crankshaft Sensor Inspection

Disconnect the crankshaft sensor lead connector (see Crankshaft Sensor Removal).
Set the hand tester [A] to the × 10 Ω range and connect it to the crankshaft sensor lead connector [B].

Special Tool - Hand Tester: 57001-1394

Crankshaft Sensor Resistance Connections: Meter (+) → Y lead Meter (–) → BK lead Standard: 376 564 Ω

Crankshaft Sensor Inspection

If there is more resistance than the specified value, the coil has an open lead and must be replaced. Much less than this resistance means the coil is shorted, and must be replaced.

Using the highest resistance range of the tester, measure the resistance between the crankshaft sensor leads and chassis ground.

Any tester reading less than infinity (∞) indicates a short, necessitating replacement of the crankshaft sensor.

Crankshaft Sensor Installation

Apply a non-permanent locking agent to the crankshaft sensor bolts [A]. Tighten: Torque - Crankshaft Sensor Bolts: 5.9 N·m (0.60 kgf·m, 52 in·lb) Using a high flash-point solvent, clea ...

Crankshaft Sensor Peak Voltage Inspection

NOTE Be sure the battery is fully charged. Using the peak voltage adapter [A] is more reliable way to determine the condition of the crankshaft sensor than crankshaft sensor internal resista ...
