Component Inspection

Reconnect the CMPS and PCM connectors.
Set up an oscilloscope as follows :
Channel A (+): terminal 2 of the CKPS, (-): ground

Channel B (+): terminal 2 of the CMPS, (-): ground
Start the engine and check for signal waveform whether synchronize with CKPS or not and tooth is missing.

Is the signal waveform normal?
YES
- Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and go to VERIFICATION OF VEHICLE REPAIR procedure.
NO
- Remove CMP and calculate air gap[1.8 mm(0.07in)]. Readjust and repair as necessary and go to VERIFICATION OF VEHICLE REPAIR procedure. If OK, check CMPS for contamination, deterioration, or damage. Substitute with a known-good CMPS and check for proper operation. If the problem is corrected, replace CMPS and then go to VERIFICATION OF VEHICLE REPAIR procedure.
