Crankshaft Sensor Peak Voltage Check

NOTE

○Be sure the battery is fully charged.

•Connect[B]. the peak voltage adapter [A] to the hand tester

Special Tool - Peak Voltage Adapter: 57001-1415 Type: KEK-54-9-B

•Connect the adapter the crankshaft sensor lead connec- tor [C], using the needle adapter set [D].

Special Tools - Hand Tester: 57001-1394 Needle Adapter Set: 57001-1457

Connections

	Adapter	Adapter
	(R, +)	(BK, –)
Crankshaft Sensor:	G	←→ BL

Hand Tester Range: × DC 10 V

•Turn the ignition switch on and push the lanyard key under the stop button.

•Pushing the starter button, crank the engine 4 ∼ 5 seconds to measure the crankshaft sensor peak voltage.

○Do not operate the starter for longer than 5 seconds. Wait 15 seconds before using it again.

•Repeat the measurements 5 or more times.

Crankshaft Sensor Peak Voltage

Standard: 2.5 V or more

If the reading is less than the specified value, check the crankshaft sensor (see Crankshaft Sensor Inspection).

Camshaft Position Sensor Peak Voltage Inspection

•Remove:

Seat (see Hull/Engine Hood chapter)

•Set the digital meter [B] to the 10 V DC range.

•Connect the peak voltage adapter [C] to the digital meter.

Special Tool - Peak Voltage Adapter: 57001-1415 Type: KEK-54-9-B

•Connect the peak voltage adapter to the camshaft sensor lead connector [D], using the needle adapter set [A].

Special Tool - Needle Adapter Set: 57001-1457

Connections		Adapter		Hand Tester
Camshaft Sensor Lead
Black	←	Red	→	(+)
Yellow	←	Black	→	(−)

•Turn the ignition switch and engine stop switch on.

•Pushing the starter button, turn the engine 4 ∼ 5 seconds to measure the camshaft position sensor peak voltage.

•Repeat the measurement 5 or more times.

Camshaft Position Sensor Peak Voltage Standard: 0.4 V or more

If the peak voltage is lower than the standard, inspect the camshaft position sensor.
