Check PCSV
Ignition "OFF"
Measure resistance between terminals "1" and "2" of the PCSV connector.
Specification: Approx. 24.5~27.5Ω(20℃(68℉))
Check that the ground voltage is less than approx. 0.3V() and the surge voltage() is between 40 V and 60 V in the PCSV’s signal waveform.
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.
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.
