  The crankshaft sensor has no power source, and when
the engine stops, the crankshaft sensor generates no sig-
nals.
Crankshaft Sensor Removal/Installation
• Refer  to the Crankshaft Sensor Removal/Installation in
  the Electrical System chapter.
Crankshaft Sensor Resistance Inspection
• Refer to the Crankshaft Sensor Inspection in the Electrical
  System chapter.
  If the reading is within the standard, check the peak volt-
  age (see Crankshaft Sensor Peak Voltage Inspection).
Crankshaft Sensor Peak Voltage Inspection
• Refer  to the Crankshaft Sensor Peak Voltage Inspection
  in the Electrical System chapter.
  If the reading is within the standard, remove the ECU and
  check the wiring for continuity between main harness con-
  nectors.
(Checking wire for open circuit)
○Disconnect the ECU and sensor connectors.
