Component Inspection

Check FTPS

Measure the output voltage with using the vacuum gauge.

CAUTION: Be careful while you do this procedure. FTPS would be damaged if you apply vacuum excessively.

Specification:

Is the measured voltage within specification?
YES
1. Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
1. Substitute with a known-good FTPS and check for proper operation. If the problem is corrected, replace FTPS and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
