IG key OFF.
Disconnect CKPS.
Check the condition of crankshaft detecting teeth through CKPS mounting hall.
Is abnormal deformation of crankshaft detecting teeth found?
![]() | ▶ Replace crankshaft assy' or cylinder head assy' and go to "Verification of Vehicle Repair". |
![]() | ▶ Go to "CKPS waveform Inspection" as follows. |
IG key OFF.
Connect CKPS connector.
Connect an oscilloscope prove to 'Signal' terminal of CKPS connector.
Engine ON.
Monitor the signal waveform at idle and during acceleration.
Reference : signal waveform
Fig.1) This shows waveform of CKPS and CMPS simultaneously. The middle area indicates reference points of CKPS and CMPS.
☞ Injection sequence is determined based on Low and High signal of CMPS reference point as detecting cylinder position.
Is the signal waveform normal?
![]() | ▶ Go to "Verification of Vehicle Repair" procedure. |
![]() | ▶ Replaces CMPS, and go to "Verification of Vehicle Repair" procedure. |
