Component Inspection
■ Visually check CKPS and target wheel
1.

IG "OFF"

2.

Check CKPS and target wheel for deformation or damage visually

3.

Are the above items normal?

▶ Go to "Check CKPS resistance" as follows.

▶ Repair or replace it. Go to "Verification of Vehicle Repair" procedure.

■ Check CKPS
4.

IG "OFF". Disconnect CKPS connector.

5.

Measure resistance between low signal and high signal terminals of CKPS connector.(Component side)

Specifiation : 500 ~ 620Ω [20℃(68℉)]

6.

Is the measured resistance within specification ?

▶ Go to "Check signal waveform of CKPS" as follows.

▶ Substitute with a known - good CKPS and check for proper operation. If the problem is corrected, replace CKPS and go to "Verification of Vehicle Repair" procedure.

■ Check signal waveform of CKPS
7.

IG "OFF". Connect GDS.

8.

ENG running and Measure signal waveform at signal high terminal of CKPS.

Fig.1) Normal waveforms of CKPS & CMPS

9.

Is the measured siganl waveform normal?

▶ Thoroughly check connectors for poor connection, corrosion, or damage. Repair or replace as necessary. Go to "Verification of Vehicle Repair" procedure.

▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair" procedure.
