More 5k CIS freq valve type questions (+ ECU q or two too)
Well, per Phil's instructions I went to SJM's site and followed the output
tests, but still didn't hear the Freq valve hum (or wastegate solenoid for
that matter, but that's another story). I connected a DMM (on volts - no
dwell setting on mine) to the freq valve connection, and it showed about ¼
volt (0.25), which doesn't seem sufficient.
So I pulled the ECU to check the connections, and what I would guess to be
about 1-2 column cms of a viscous oily substance came out of pressure
sensor line (I guess what would amout to about 10-20 drops). I'm pretty
sure this isn't normal. I don't really want to entirely disassemble the
car, so does someone know where this line comes out on the other side of
the firewall.
BTW, from ECU pin 8 to the orange line on the freq valve shows about 10
ohms, and the blue/black line from the freq valve to ground shows about 5
ohms. As both have items inbetween, I wasn't too surprised, but glad there
was at least continuity. My parts car had almost identical values which
eased my pain a little.
Thanks,
Arryn.
