VTEC spool solenoid valve. what do i do?

 

Is it hooked up properly? Wires broken?

Give us more information. engine/ecu/car?

 

i got a D16Z6 runnin on a PR3 ecu in a 91 hcw

 

Disconnect the grey plug on the vtec solenoid.
Connect a jumper wire and connect one end to the '+' (positive) battery terminal.
Touch the other end of the jumper wire to the solenoid side of the grey 1 pin connector that you disconnected.
There should be an audible click from the solenoid.

If you get the click then remove the solenoid and clean the filter screen.

Check your vtec wiring.

 

Okay sounds good. But I have another thread out that is questioning why there is a red and white wire comin out of the back of my ecu. Idk what it is?

 

What pins on the ECU do they go to?
You should be able to search for an ECU pin-out.

 

Well I'm not at home right now. But I can tell you as soon as I get there. Would a wire being disconnected from the ecu like that throw a code and make my car idle rough, and sometimes die? Well that's beside the point, I just wanna fix the code first.

 

I got the solenoid to click. What wires should I check?

 

The one wire that runs from the vtec solenoid all the way to the pin at the ECU.

That should help you with your other wires too.

 

so that one wire that runs off the grey plug at the solenoid is my problem? if i read that diagram right, does it just run to D6?

 

Yup.
Maybe it's one of the spare wires you have?

 

Alright let's hope so. I appreciate all the help. Can I contact you if I have any more problems?
