Crankshaft Position (Ckp) Sensor Inspection; Knock Sensor Removal And Installation - Suzuki 2006 SX4 Service Manual

1C-9 Engine Electrical Devices:
Installation
Reverse removal procedure noting the following.
• Apply engine oil to O-ring of sensor.
• Tighten CKP sensor bolt to specified torque.
Tightening torque
CKP sensor bolt (a): 11 N·m (1.1 kgf-m, 8.0 lb-ft)
• Connect connector and fix wire harness with clamp
securely.

Crankshaft Position (CKP) Sensor Inspection

Waveform Check
Using oscilloscope, check that CKP sensor signal is
outputted properly referring to "Reference waveform
No.19" and "Reference waveform No.20" of "Inspection
of ECM and Its Circuits in Section 1A".
If sensor signal is outputted properly, CKP sensor is in
good condition.
Visual Check
• Check that O-ring is free from damage.
• Check that end face of sensor and signal plate tooth
are free from any metal particles and damage.
Resistance Check
Measure resistance between "1" and "2" terminals of
CKP sensor.
CKP sensor resistance
480 – 660 Ω at 20 °C, 68 °F
If measured resistance is out of specified value, replace
CKP sensor.
