ELECTRICAL SYSTEM 9-27 CKP SENSOR PEAK VOLTAGE • Remove the front seat. (8-7) NOTE: Be sure that all couplers are connected properly and the battery used is in fully-charged condition. • Disconnect the both couplers 1. • Connect the multi-circuit tester with peak volt adaptor as fol- lows. • Measure the CKP sensor peak voltage between Green/Blue and Green/White lead wires at the ECM coupler (Black) A. G/W wire (+ Probe) – G/Bl wire (- Probe) 09900-25008: Multi-circuit tester set G/W 09900-25009: Needle pointed probe set A Black coupler  G/Bl Before using the multi-circuit tester and peak volt adaptor, be sure to refer to the appropriate instruction manual. E • Shift the transmission into the neutral and turn ignition switch “ON”. L ECM • Crank the engine a few seconds with the starter motor by CKP sensor coupler P coupler G/W depressing starter button and check the CKP sensor peak G/Bl W voltage. M G/W • Repeat the above test procedure a few times and measure CKP sensor Peak the highest peak voltage. A volt Tester knob indication: Voltage () adaptor S CKP sensor peak voltage: 0.5 V and more (Green/Blue – Green/White)
