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 (see Crankshaft Sensor Removal).
• Set the hand tester [B] to the DC 10 V range, and connect it peak voltage adapter.

• Connect the adapter to the terminals of the crankshaft sensor lead connector [C].

• Turn the engine stop switch to run position.
• Turn the ignition switch to ON.
• Pushing the starter button, turn the engine 4 ∼ 5 seconds with the transmission in neutral to measure the peak voltage.
• Repeat the measurements 5 times or more times.

Crankshaft Sensor Peak Voltage Standard: 1.9 V or more

If the reading is less than the standard, inspect the crankshaft sensor (see Crankshaft Sensor Inspection).
