Be sure the battery is fully charged.
Hand Tester Range:
Turn the ignition switch and the engine stop switch ON.
Pushing the starter button, turn the engine 4
with the transmission in neutral to measure the crankshaft
sensor peak voltage.
Repeat the measurements 5 or more times for one crank-
Repeat the test for the other crankshaft sensor.
Crankshaft Sensor Peak Voltage
2.2 V or more
2.0 V or more
If the reading is less than the specified value, replace the
If the reading is normal, check the ECU (see Fuel System
If the peak voltage adapter is not available, the coil can
be checked for a broken or badly shorted winding with the
hand tester (special tool).
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.
Set the hand tester [A] to the × 100 Ω range and wire it to
the crankshaft sensor lead connector [B].
If there is more resistance than the specified value, the
coil has an open wire and must be replaced. Much less
than this resistance means the coil is shorted, and must
Crankshaft Sensor Resistance: Standard: 380
Using the highest resistance range of the tester, measure
the resistance between the crankshaft sensor wires and
Any tester reading less than infinity (∞) indicates a short,
necessitating replacement of the crankshaft sensor assy.
