Can someone tell me if the vacuum at the two way valve that is on the filler neck in the rear wheel well strong or weak?
Also, do you have a pin 21 on your ECU?
I've been troubleshooting my EVAP Valve CEL. I have had the thing smoke checked, no leaks. And the valve operates as it should, and is within it's 40+-20 ohm according to specs (OBD1).
I see two options. 1) The fact that I have NO pin 21 at my ECU, I should add it. No disconnected wires.
2) I have a vacuum problem that is a mistory and the same when either of my two charcoal canisters is present.
Below is my long long discription if you feel like reading it:
