Component Inspection

■ Visual Check 

1. IG KEY "OFF".
2. Check physical condition of CMPS.
3. Check the projection of camshaft visually after remove the CMPS.
4. Is everything O.K?

   YES 

   • Go to "CMPS check" procedure below.

   NO 

   • Repair as necessary and then, go to "VERIFICATION OF VEHICLE REPAIR " procedure.

■ Check signal waveform of CMPS 

1. Set up an oscilloscope as follows:
   • Channel A (+): Signal terminal of the CMPS #1 (back probe), (-): ground
2. Start the engine and check for signal waveform compared with reference waveform below.

   Specification:  Refer to SIGNAL WAVEFORM & DATA 

3. 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 CMPS and check for air gap. Readjust as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
   • If CKP synchronization fails, check that the crankshaft and camshaft are correctly aligned the matching marks of the pulleys. Repair or readjust as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
   • 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.
