Component Inspection

Component Inspection

1. Check PCSV
(1) Ignition "OFF"
(2) Remove PCSV and check it for open stuck or leak
(3) Measure resistance between terminals "1" and "2" of the PCSV connector.
Specification: Approx. 19.0 - 22.0 Ohms
(4) Connect Scantool and Perform ACTUATION TEST for PCSV with scantool
(5) Check that clicking sound can be heard by actuation test.




(6) Monitor the PCSV signal waveform and verify that the ground voltage is less than approx. 0.3V (1) and the surge voltage (2) is between 40V and 60V.




(7) Is the PCSV normal?
YES
- Substitute with a known - good PCM and check for proper operation.
- If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair" procedure.

CAUTION:
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others.

NO
- Substitute with a known - good PCSV and check for proper operation.
- If the problem is corrected, replace PCSV and go to "Verification of Vehicle Repair" procedure.
