Component Inspection

Check CKPS
1. IG "OFF" and disconnect CKPS connector.
2. Measure resistance between terminals 1 and 2 of CKPS connector. (Component side)

3. Is the measured resistance within specification?
  YES
  - Go to 2"Check signal waveform of CKPS" as follows.
  NO
  - 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
1. IG "OFF" and connect scan tool.
2. ENG "ON" and Measure signal waveform at terminal 1 or 2 of CKPS.

3. Is the measured signal waveform normal?
  YES
  - Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary, and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - 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.
NOTE: There is a memory reset function on scan tool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function before reusing the PCM
