Crankshaft Sensor Inspection
•
Disconnect the crankshaft sensor lead connector (see
Crankshaft Sensor Removal).
•
Set the hand tester [A] to the × 100 Ω range and connect
it to the crankshaft sensor lead connector [B].
Special Tool - Hand Tester: 57001-1394
Crankshaft Sensor Resistance: 380 ∼ 570 Ω
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 Peak Voltage Inspection
NOTE
○
Be sure the battery is fully charged.
○
Using the peak voltage adapter is a more reliable way
to determine the condition of the crankshaft sensor than
crankshaft sensor internal resistance measurements.
•
Disconnect the crankshaft sensor lead connector (see
Crankshaft Sensor Removal).
•
Set the hand tester [A] to the × 25 V DC range, and con-
nect the peak voltage adapter [B].
Special Tools - Hand Tester: 57001-1394
Peak Voltage Adapter: 57001-1415
Type: KEK-54-9-B
•
Connect the black lead (–) [C] of the adapter to yellow
lead and red lead (+) [D] to black lead in the crankshaft
sensor connector [E].
•
Turn the ignition switch and engine stop switch ON.
•
Pushing the starter button, turn the engine 4 ∼ 5sec-
onds with the transmission gear in neutral to measure the
crankshaft sensor peak voltage.
•
Repeat the measurement 5 or more times.
Crankshaft Sensor Peak Voltage
Standard:
3.2 V or more
If the tester reading is not specified one, check the crank-
shaft sensor.
