Crankshaft Sensor Inspection
• Disconnect  the crankshaft sensor lead connector (see
  Crankshaft Sensor Removal).
• Set a tester [A], and connect it to the crankshaft sensor
  lead connector [B].
    Special Tool - Needle Adapter Set [C]: 57001-1457

    Crankshaft Sensor Resistance
      Connections:
        Tester (+) → Y lead
        Tester (–) → BK lead
      Standard:      376 ∼ 564 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.
•   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 [A] is more reliable way
      to determine the condition of the crankshaft sensor than
      crankshaft sensor internal resistance measurements.

• Disconnect  the crankshaft sensor lead connector [B] (see
  Alternator Cover Removal).
• Set a tester [C], and connect it peak voltage adapter.
    Special Tools - Peak Voltage Adapter: 57001-1415
                    Type: KEK-54-9-B
                    Needle Adapter Set [D]: 57001-1457
• Connect  the adapter to the terminals of the crankshaft
  sensor lead connector.
    Connections:
       Crankshaft             Peak Voltage
                                                     Tester
      Sensor Lead               Adapter
         Y lead       ←          R lead       →        (+)
         BK lead      ←         BK lead       →        (–)

• Turn the engine stop switch to run position.
• Turn the ignition switch on.
• onds withthe
  Pushing       starter button, turn the engine 4 ∼ 5 sec-
            the transmission gear in neutral to measure the
    crankshaft sensor peak voltage.
•   Repeat the measurement 5 or more times.
    Crankshaft Sensor Peak Voltage
      Standard:   2.0 V or more
    If the reading is less than the standard, inspect the crank-
    shaft sensor (see Crankshaft Sensor Inspection).
