N75 cable issue

[Billman]

I have a problem with the n75 valve. I think the cable has a problem somewhere and it does not work all the time. I tried another valve and it behaved the same.

How can it test it somehow stationary so I can look for the faulty place?

well on the read cable must have +12v when the ignition is ON (or engine runing- dont remember).
and thy yellow on cable is connected with ECU pin 33.

I think the n75 cables are green and blue.

maybe on S2..
on my 200 20v and s6 are red and yellow. newer mind.. one must be +12v other on pin 33. you will see which it is...
good luck !

Try the ECU output tests, as described here:

i have an aftermarket ECU but maybe i am gonna be able to test it while changing its settings.
