Default After jacking the engine up I now have a small EVAP leak

when I jacked up the engine to change the control arms I somehow disconnected a vac line somewhere. When the car idles for about 3 minutes at operating temp it will make a puffing noise. Like a steam engine. Cha cha cha cha. You get the point.

It throws a CEL saying EVAP leak (small). All I disconnected was the main intake pipe, front motor mount and top torque mount. I lifted the motor about 6 inches. I DID remember to hookup the larger vac hose that Im assuming goes to the PCV system by the throttle body.

I'm guessing that this hose that is leaking goes to the charcoal canister if the car has one. It sounds like the noise is coming from the front passenger side area. I can't trace it though. It's not a constant sucking noise, sounds like a solenoid is switching It on/off.

Any guesses?

Check by the valve on the cooling fan on the drivers side. If that one is attached check the connection just behind the subframe on the passenger side under the car.

The valve that's actually mounted to the fan shroud? That one has both lines still attached. Am I looking for the other end of that valve? I can't find any decent vac diagrams for this car. I hate to be a newb but can you be a tad bit more specific of the location? Look for it from under the car or above?

Thanks tech!

There is the rear subframe bolt on the passenger side. Like a foot or so back from the rear control arm bolt. There should be a hard plastic line that has a break and a rubber hose holding it together. See if that junction came apart.

It is possible there is a hose from the intake to the evap valve.
