IG "OFF". Disconnect CKPS connector.
Measure resistance between low signal and high signal terminals of CKPS connector.(Component side)
Specification : 500 ~ 620Ω [20℃(68℉)]
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. |
IG "OFF". Connect GDS.
Engine running. Measure signal waveform at signal terminal of CKPS.
Fig.1) Normal waveforms of CKPS & CMPS
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. |
