ELECTRICAL SYSTEM 9-27
CKP SENSOR PEAK VOLTAGE
NOTE:
Be sure that all couplers are connected properly and the battery
used is in fully-charged condition.
• Lift and support the fuel tank. (5-3)
• Disconnect the CKP sensor lead wire coupler and connect
the multi-circuit tester with the peak volt adaptor as follows.
B wire ( Probe) – G wire ( Probe)
09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
• Shift the transmission into the neutral and turn the ignition
switch ON.
• Crank the engine a few seconds with the starter motor by
depressing starter button and check the CKP sensor peak
voltage at the CKP sensor coupler.
• Repeat the above test procedure a few times and measure
the highest peak voltage.
• Measure the CKP sensor peak voltage at the ECM coupler
( and terminals). (4-39)
Tester knob indication: Voltage ()
CKP sensor peak voltage: 0.5 V and more (G – B)
If the peak voltage is lower than the standard range, check the
coupler connection or replace the CKP sensor and inspect it
again.
CKP SENSOR RESISTANCE
• Measure the resistance between the lead wires and ground. If
the resistance is not as specified, the CKP sensor must be
replaced.
09900-25008: Multi-circuit tester set
Tester knob indication: Resistance (Ω)
CKP sensor resistance:142 – 194 Ω (G – B)
∞Ω (G – Ground)
Before using the multi-circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruction
manual.
