• Shift the transmission into the neutral and turn ignition switch
“ON”.
• Crank the engine a few seconds with the starter motor by
depressing starter button and check the CKP sensor peak
voltage.
• Repeat the above procedure a few times and measure the
highest peak voltage.

If the peak voltage on the CKP sensor lead wire coupler is OK
but on the ECM coupler is out of specification, the wire harness
must be replaced. If both peak voltages are out of specification,
the CKP sensor must be replaced and re-checked.

• Measure the resistance between the lead wires and ground. If
the resistance is not specified value, the CKP sensor must be
replaced.
