Component Inspection

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

      SPECIFICATION: 

      RESISTANCE REFERENCE CHART

      Resistance 700 ± 70Ω
      Fig 1: Measuring Resistance Between Terminals 1 And 2 Of CKPS Connector
      G04879844
    3. Is the measured resistance within specification?

      YES 

      • Go to " 2Check 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.
  2. Check signal waveform of CKPS
    1. IG "OFF" and connect scantool.
    2. ENG "ON" and Measure signal waveform at terminal 1 or 2 of CKPS.

      REFERENCE SIGNAL WAVEFORM: 

      Fig 2: Identifying Signal Waveform
      G04879842
    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 scantool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others
