SHOW CAPTION HIDE CAPTION A tech searches for COunder the hood using the Smoke Wizar No.


And from there, we can do pinpoint testing on the individual components within that system to get to the root cause. For example, if you do have an EVAP emissions code, we would test for leaks in the fuel cap area, the fuel filler hose, the evap canister, your fuel tank, fuel lines, evap hoses, and the purge or vent valve. We know our parts and products. We Also Offer Smoke Boost Leak Testers. Smoke Testing Is Very Effective And Affordable.

An EVAP leak is a fault in the evaporative emission control system ( EVAP ). The EVAP ’s function is to keep gasoline fumes in the fuel tank from reaching the atmosphere.


This keeps air pollution down and keeps the smell of fuel. The smoke machine pushes the smoke through the system , so that any leak can be visually detected.

Have evap issues, so replaced the gas cap, and filler neck tube going to the gas tank. Evaporative Emission Control ( EVAP ) System. Performed second smoke test and still get smoke coming out of the gas cap area. In fact, virtually all automakers that have approved the use of smoke vapor. Evap System Hose– The hose that carries the fuel vapor from the fuel tank to the intake manifold can begin to leak.


Ran smoke test - can see that there is a little pressure loss but can not find leak. Next, we connected our smoke machine, which we use to check for EVAP leaks. Again, using the diagnostic tool, we commanded the vent solenoid on (which closes the valve this valve is normally off and thus open, to do the test it must be On, meaning the vent is close so as to allow the system to hold the smoke in), and tested the system.

The fuel tank should have less than the fuel tank capacity to properly test the evap system. The fuel evaporative system ( EVAP ) controls emission by housing vapors from evaporated fuel and sending them back to the fuel tank to be reused. The labor alone will cost somewhere between $and $14 while parts will run somewhere between $1and $440. Connect shop air to the EELD.


A smoke machine is used to identify leaks in systems that hold and transfer air and vapor. EVAP System testing using a Smoke Machine. Guessing at parts can get VERY expensive. The ECM commands the EVAP Purge Solenoid OFF once the system has reached a predetermined level of vacuum.
