PCSV general info:
PCSV is a duty cycle solenoid, normally closed, operated by ECM ground. Depending on manufacture, it has 25-35 Ohms resistance at 20*C. It opens and closes about 70 times within a minute when idling or higher, within engine operating temperature, and should never be in stuck open position = problems and DTC will be set for 100%. Will not operate at WOTh.

Above advanced OBD II version caused some confusion among members.
Here is CB1100 version, which does not follow OBD II protocol::
PCSV is a duty cycle solenoid, normally closed, operated by ECM ground with 33 Ohms resistance at 20*C. It opens and closes multiple times within a minute when idling or higher, and should never be in stuck open position. Shop manual does not provide DTC for PCSV malfunctions
Sorry for this confusion = my bad
