Ckp Sensor Inspection - Suzuki kq750 Service Manual

1H-5 Ignition System:
3) Measure the ignition coil resistance in both the
primary and secondary coils. If the resistance is not
within the standard range, replace the ignition coil
with a new one.
Special tool

Resistance (Ω)
Ignition coil resistance
Primary: 0.1 – 0.6 Ω ((+) terminal – (–) Ground)
Secondary: 12 – 19 kΩ (Spark plug cap – (–)
terminal)

4) After measuring the ignition coil resistance, reinstall
the removed parts.

CKP Sensor Inspection

Refer to "Electrical Components Location in Section 0A
(Page 0A-7)".
CKP Sensor Peak Voltage
1) Remove the left side cover and engine side cover.
Refer to "Front Side Exterior Parts Removal and
Installation in Section 9D (Page 9D-6)".
2) Disconnect the CKP sensor coupler (1).
NOTE
Be sure that all of the couplers are connected
properly and the battery is fully-charged.

3) Connect the multi-circuit tester with the peak volt
adaptor as follows:
CAUTION
!
Before using the multi-circuit tester and peak
voltage adaptor, refer to the appropriate
instruction manual.

4) Measure the CKP sensor peak voltage in the
following procedures:
a) Shift the transfer to the neutral, turn the ignition
switch ON.
b) Press the starter button and allow the engine to
crank for a few seconds, and then measure the
CKP sensor peak voltage.
5) Repeat the b) procedure a few times and measure
the highest CKP sensor peak voltage.

5.0 V and more (Blue – White)
6) If the peak voltage is within the specification, check
the continuity between the CKP sensor coupler and
ECM coupler.
CAUTION
!
Normally, use the needle pointed probe to the
backside of the lead wire coupler to prevent
the terminal bend and terminal alignment.
7) After measuring the CKP sensor peak voltage,
reinstall the removed parts.
