Component Inspection

Reconnect the CMPS and ECM 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
1. Check for poor connection between ECM 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
1. Remove CMP and calculate air gap (1.8mm (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.
