Question about Volvo Cars & Trucks
Had a p0455 large leak. I did a evap smoke test on a 2001 s60 Volvo non turbo, and the smoke was coming out of a round 3" long, with a little nipple on it object at the right rear just in front of the back bumper and behind the gas filler tube. Does anyone know what this part is and should I just plug it off.
This is probably the EVAP canister purge valve and if it is it will need replacing as it is part of the fuel system and may lead to venting in the tank problems and that will be misfiring, low fuel pressure problems and pump problems .. Take it to an accredited mechanic with Volvo experience and discuss if that is what it is .

SOURCE: code p0455 evap emission (large)
have the gas cap tested or just replace it, then disconnect the battery for 5 minutes to reset the code, then drive it for a few miles and see if problem comes back, if it does a trip to the dealer is in order, as this may be covered by your emission warranty which is good for 70,000 miles.

The EVAP control sytem is checked by the ECM upon the first start of the day when the engine is cool and will trigger the DTC code P0445. If you have a vacuum line leak when it's cold and seals it self when it warms up then the code will stay there. After warming up the car reset the ECM to clear any DTC codes and see if any MILL shows up. IF not then there is a leak only when the system is cold so your going to have to try to do a smoke test when the system is cold.
The other thing is to check all the vacuum lines and fittings around the canister and fuel tank for any lose clamps ECT.
Good luck and keep me posted. Be glad to help you

SOURCE: 2001 Alero code p0440.
there is still a small leak, the shop thats doing the testing can repair it? right? Usually these things are just one item, you may have more than one.

your problem is probably a vacuum hose that goes from the purge valve to the gas tank (crack or broken hose). There should be two of these check both. A broken vacuum line will make the purge valve make a clicking noise that can be mistaken for noisy engine valves.
